CVE-2026-33297 WRITEUP CRITICAL WRITEUP
AVideo has an IDOR - Any Admin Can Set Another User's Channel Password via setPassword.json.php
WWBN AVideo is an open source video platform. Prior to version 26.0, the `setPassword.json.php` endpoint in the CustomizeUser plugin allows administrators to set a channel password for any user. Due to a logic error in how the submitted password value is processed, any password containing non-numeric characters is silently coerced to the integer zero before being stored. This means that regardless of the intended password, the stored channel password becomes 0, which any visitor can trivially guess to bypass channel-level access control. Version 26.0 contains a patch for the issue.
CVSS 9.1
CVE-2026-33351 WRITEUP CRITICAL WRITEUP
AVideo has Unauthenticated SSRF via `webSiteRootURL` Parameter in saveDVR.json.php, Chaining to Verification Bypass
WWBN AVideo is an open source video platform. Prior to version 26.0, a Server-Side Request Forgery (SSRF) vulnerability exists in `plugin/Live/standAloneFiles/saveDVR.json.php`. When the AVideo Live plugin is deployed in standalone mode (the intended configuration for this file), the `$_REQUEST['webSiteRootURL']` parameter is used directly to construct a URL that is fetched server-side via `file_get_contents()`. No authentication, origin validation, or URL allowlisting is performed. Version 26.0 contains a patch for the issue.
CVSS 9.1
CVE-2026-33352 WRITEUP CRITICAL WRITEUP
AVideo has an Unauthenticated SQL Injection via `doNotShowCats` Parameter (Backslash Escape Bypass)
WWBN AVideo is an open source video platform. Prior to version 26.0, an unauthenticated SQL injection vulnerability exists in `objects/category.php` in the `getAllCategories()` method. The `doNotShowCats` request parameter is sanitized only by stripping single-quote characters (`str_replace("'", '', ...)`), but this is trivially bypassed using a backslash escape technique to shift SQL string boundaries. The parameter is not covered by any of the application's global input filters in `objects/security.php`. Version 26.0 contains a patch for the issue.
CVSS 9.8
CVE-2026-33354 WRITEUP HIGH WRITEUP
AVideo has an authenticated arbitrary local file read via `chunkFile` path injection in `aVideoEncoder.json.php`
WWBN AVideo is an open source video platform. In versions up to and including 26.0, `POST /objects/aVideoEncoder.json.php` accepts a requester-controlled `chunkFile` parameter intended for staged upload chunks. Instead of restricting that path to trusted server-generated chunk locations, the endpoint accepts arbitrary local filesystem paths that pass `isValidURLOrPath()`. That helper allows files under broad server directories including `/var/www/`, the application root, cache, tmp, and `videos`, only rejecting `.php` files. For an authenticated uploader editing their own video, this becomes an arbitrary local file read. The endpoint copies the attacker-chosen local file into the attacker's public video storage path, after which it can be downloaded over HTTP. Commit 59bbd601a3f65a5b18c1d9e4eb11471c0a59214f contains a patch for the issue.
CVSS 7.6
CVE-2026-33478 WRITEUP CRITICAL WRITEUP
AVideo Multi-Chain Attack: Unauthenticated Remote Code Execution via Clone Key Disclosure, Database Dump, and Command Injection
WWBN AVideo is an open source video platform. In versions up to and including 26.0, multiple vulnerabilities in AVideo's CloneSite plugin chain together to allow a completely unauthenticated attacker to achieve remote code execution. The `clones.json.php` endpoint exposes clone secret keys without authentication, which can be used to trigger a full database dump via `cloneServer.json.php`. The dump contains admin password hashes stored as MD5, which are trivially crackable. With admin access, the attacker exploits an OS command injection in the rsync command construction in `cloneClient.json.php` to execute arbitrary system commands. Commit c85d076375fab095a14170df7ddb27058134d38c contains a patch.
CVSS 10.0
CVE-2026-33479 WRITEUP HIGH WRITEUP
AVideo has PHP Code Injection via eval() in Gallery saveSort.json.php Exploitable Through CSRF Against Admin
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the Gallery plugin's `saveSort.json.php` endpoint passes unsanitized user input from `$_REQUEST['sections']` array values directly into PHP's `eval()` function. While the endpoint is gated behind `User::isAdmin()`, it has no CSRF token validation. Combined with AVideo's explicit `SameSite=None` session cookie configuration, an attacker can exploit this via cross-site request forgery to achieve unauthenticated remote code execution — requiring only that an admin visits an attacker-controlled page. Commit 087dab8841f8bdb54be184105ef19b47c5698fcb contains a patch.
CVSS 8.8
CVE-2026-33480 WRITEUP HIGH WRITEUP
AVideo has a SSRF Protection Bypass via IPv4-Mapped IPv6 Addresses in Unauthenticated LiveLinks Proxy
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `isSSRFSafeURL()` function in AVideo can be bypassed using IPv4-mapped IPv6 addresses (`::ffff:x.x.x.x`). The unauthenticated `plugin/LiveLinks/proxy.php` endpoint uses this function to validate URLs before fetching them with curl, but the IPv4-mapped IPv6 prefix passes all checks, allowing an attacker to access cloud metadata services, internal networks, and localhost services. Commit 75ce8a579a58c9d4c7aafe453fbced002cb8f373 contains a patch.
CVSS 8.6
CVE-2026-33482 WRITEUP HIGH WRITEUP
AVideo has an OS Command Injection via $() Shell Substitution Bypass in sanitizeFFmpegCommand()
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `sanitizeFFmpegCommand()` function in `plugin/API/standAlone/functions.php` is designed to prevent OS command injection in ffmpeg commands by stripping dangerous shell metacharacters (`&&`, `;`, `|`, `` ` ``, `<`, `>`). However, it fails to strip `$()` (bash command substitution syntax). Since the sanitized command is executed inside a double-quoted `sh -c` context in `execAsync()`, an attacker who can craft a valid encrypted payload can achieve arbitrary command execution on the standalone encoder server. Commit 25c8ab90269e3a01fb4cf205b40a373487f022e1 contains a patch.
CVSS 8.1
CVE-2026-33483 WRITEUP HIGH WRITEUP
AVideo Affected by Unauthenticated Disk Space Exhaustion via Unlimited Temp File Creation in aVideoEncoderChunk.json.php
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `aVideoEncoderChunk.json.php` endpoint is a completely standalone PHP script with no authentication, no framework includes, and no resource limits. An unauthenticated remote attacker can send arbitrary POST data which is written to persistent temp files in `/tmp/` with no size cap, no rate limiting, and no cleanup mechanism. This allows trivial disk space exhaustion leading to denial of service of the entire server. Commit 33d1bae6c731ef1682fcdc47b428313be073a5d1 contains a patch.
CVSS 7.5
CVE-2026-33485 WRITEUP HIGH WRITEUP
AVideo has an Unauthenticated Blind SQL Injection in RTMP on_publish Callback via Stream Name Parameter
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the RTMP `on_publish` callback at `plugin/Live/on_publish.php` is accessible without authentication. The `$_POST['name']` parameter (stream key) is interpolated directly into SQL queries in two locations — `LiveTransmitionHistory::getLatest()` and `LiveTransmition::keyExists()` — without parameterized binding or escaping. An unauthenticated attacker can exploit time-based blind SQL injection to extract all database contents including user password hashes, email addresses, and other sensitive data. Commit af59eade82de645b20183cc3d74467a7eac76549 contains a patch.
CVSS 7.5
CVE-2026-33488 WRITEUP HIGH WRITEUP
AVideo has a PGP 2FA Bypass via Cryptographically Broken 512-bit RSA Key Generation in LoginControl Plugin
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `createKeys()` function in the LoginControl plugin's PGP 2FA system generates 512-bit RSA keys, which have been publicly factorable since 1999. An attacker who obtains a target user's public key can factor the 512-bit RSA modulus on commodity hardware in hours, derive the complete private key, and decrypt any PGP 2FA challenge issued by the system — completely bypassing the second authentication factor. Additionally, the `generateKeys.json.php` and `encryptMessage.json.php` endpoints lack any authentication checks, exposing CPU-intensive key generation to anonymous users. Commit 00d979d87f8182095c8150609153a43f834e351e contains a patch.
CVSS 7.4
CVE-2026-33492 WRITEUP HIGH WRITEUP
AVideo has Session Fixation via GET PHPSESSID Parameter With Disabled Login Session Regeneration
WWBN AVideo is an open source video platform. In versions up to and including 26.0, AVideo's `_session_start()` function accepts arbitrary session IDs via the `PHPSESSID` GET parameter and sets them as the active PHP session. A session regeneration bypass exists for specific blacklisted endpoints when the request originates from the same domain. Combined with the explicitly disabled session regeneration in `User::login()`, this allows a classic session fixation attack where an attacker can fix a victim's session ID before authentication and then hijack the authenticated session. Commit 5647a94d79bf69a972a86653fe02144079948785 contains a patch.
CVSS 7.3
CVE-2026-33493 WRITEUP HIGH WRITEUP
AVideo has a Path Traversal in import.json.php that Allows Private Video Theft and Arbitrary File Read/Deletion via fileURI Parameter
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `objects/import.json.php` endpoint accepts a user-controlled `fileURI` POST parameter with only a regex check that the value ends in `.mp4`. Unlike `objects/listFiles.json.php`, which was hardened with a `realpath()` + directory prefix check to restrict paths to the `videos/` directory, `import.json.php` performs no directory restriction. This allows an authenticated user with upload permission to: (1) steal any other user's private video files by importing them into their own account, (2) read `.txt`/`.html`/`.htm` files adjacent to any `.mp4` file on the filesystem, and (3) delete `.mp4` and adjacent text files if writable by the web server process. Commit e110ff542acdd7e3b81bdd02b8402b9f6a61ad78 contains a patch.
CVSS 7.1
CVE-2026-33499 WRITEUP MEDIUM WRITEUP
AVideo has Reflected XSS via unlockPassword Parameter in forbiddenPage.php and warningPage.php
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `view/forbiddenPage.php` and `view/warningPage.php` templates reflect the `$_REQUEST['unlockPassword']` parameter directly into an HTML `<input>` tag's attributes without any output encoding or sanitization. An attacker can craft a URL that breaks out of the `value` attribute and injects arbitrary HTML attributes including JavaScript event handlers, achieving reflected XSS against any visitor who clicks the link. Commit f154167251c9cf183ce09cd018d07e9352310457 contains a patch.
CVSS 6.1
CVE-2026-33500 WRITEUP MEDIUM WRITEUP
AVideo Vulnerable to Stored XSS via Markdown `javascript:` URI Bypasses ParsedownSafeWithLinks Sanitization
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the fix for CVE-2026-27568 (GHSA-rcqw-6466-3mv7) introduced a custom `ParsedownSafeWithLinks` class that sanitizes raw HTML `<a>` and `<img>` tags in comments, but explicitly disables Parsedown's `safeMode`. This creates a bypass: markdown link syntax `[text](javascript:alert(1))` is processed by Parsedown's `inlineLink()` method, which does not go through the custom `sanitizeATag()` sanitization (that only handles raw HTML tags). With `safeMode` disabled, Parsedown's built-in `javascript:` URI filtering (`sanitiseElement()`/`filterUnsafeUrlInAttribute()`) is also inactive. An attacker can inject stored XSS via comment markdown links. Commit 3ae02fa240939dbefc5949d64f05790fd25d728d contains a patch.
CVSS 5.4
CVE-2026-33501 WRITEUP MEDIUM WRITEUP
AVideo has Unauthenticated Information Disclosure of User Group Permission Mappings via Permissions Plugin
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the endpoint `plugin/Permissions/View/Users_groups_permissions/list.json.php` lacks any authentication or authorization check, allowing unauthenticated users to retrieve the complete permission matrix mapping user groups to plugins. All sibling endpoints in the same directory (`add.json.php`, `delete.json.php`, `index.php`) properly require `User::isAdmin()`, indicating this is an oversight. Commits dc3c825734628bb32550d0daa125f05bacb6829c and b583acdc9a9d1eab461543caa363e1a104fb4516 contain patches.
CVSS 5.3
CVE-2026-33502 WRITEUP CRITICAL WRITEUP
AVideo has Unauthenticated SSRF via plugin/Live/test.php
WWBN AVideo is an open source video platform. In versions up to and including 26.0, an unauthenticated server-side request forgery vulnerability in `plugin/Live/test.php` allows any remote user to make the AVideo server send HTTP requests to arbitrary URLs. This can be used to probe localhost/internal services and, when reachable, access internal HTTP resources or cloud metadata endpoints. Commit 1e6cf03e93b5a5318204b010ea28440b0d9a5ab3 contains a patch.
CVSS 9.3
CVE-2026-33507 WRITEUP HIGH WRITEUP
AVideo Affected by CSRF on Plugin Import Endpoint Enables Unauthenticated Remote Code Execution via Malicious Plugin Upload
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `objects/pluginImport.json.php` endpoint allows admin users to upload and install plugin ZIP files containing executable PHP code, but lacks any CSRF protection. Combined with the application explicitly setting `session.cookie_samesite = 'None'` for HTTPS connections, an unauthenticated attacker can craft a page that, when visited by an authenticated admin, silently uploads a malicious plugin containing a PHP webshell, achieving Remote Code Execution on the server. Commit d1bc1695edd9ad4468a48cea0df6cd943a2635f3 contains a patch.
CVSS 8.8
CVE-2026-33292 WRITEUP HIGH WRITEUP
AVideo has Authorization Bypass via Path Traversal in HLS Endpoint Allows Streaming Private/Paid Videos
WWBN AVideo is an open source video platform. Prior to version 26.0, the HLS streaming endpoint (`view/hls.php`) is vulnerable to a path traversal attack that allows an unauthenticated attacker to stream any private or paid video on the platform. The `videoDirectory` GET parameter is used in two divergent code paths — one for authorization (which truncates at the first `/` segment) and one for file access (which preserves `..` traversal sequences) — creating a split-oracle condition where authorization is checked against one video while content is served from another. Version 26.0 contains a fix for the issue.
CVSS 7.5
CVE-2026-33293 WRITEUP HIGH WRITEUP
AVideo Affected by Arbitrary File Deletion via Path Traversal in CloneSite deleteDump Parameter
WWBN AVideo is an open source video platform. Prior to version 26.0, the `deleteDump` parameter in `plugin/CloneSite/cloneServer.json.php` is passed directly to `unlink()` without any path sanitization. An attacker with valid clone credentials can use path traversal sequences (e.g., `../../`) to delete arbitrary files on the server, including critical application files such as `configuration.php`, causing complete denial of service or enabling further attacks by removing security-critical files. Version 26.0 fixes the issue.
CVSS 8.1
CVE-2026-33294 WRITEUP MEDIUM WRITEUP
AVideo has SSRF in BulkEmbed Thumbnail Fetch that Allows Reading Internal Network Resources
WWBN AVideo is an open source video platform. Prior to version 26.0, the BulkEmbed plugin's save endpoint (`plugin/BulkEmbed/save.json.php`) fetches user-supplied thumbnail URLs via `url_get_contents()` without SSRF protection. Unlike all six other URL-fetching endpoints in AVideo that were hardened with `isSSRFSafeURL()`, this code path was missed. An authenticated attacker can force the server to make HTTP requests to internal network resources and retrieve the responses by viewing the saved video thumbnail. Version 26.0 fixes the issue.
CVSS 5.0
CVE-2026-33295 WRITEUP MEDIUM WRITEUP
AVideo Vulnerable to Stored XSS via Unescaped Video Title in CDN downloadButtons.php
WWBN AVideo is an open source video platform. Prior to version 26.0, WWBN/AVideo contains a stored cross-site scripting vulnerability in the CDN plugin's download buttons component. The `clean_title` field of a video record is interpolated directly into a JavaScript string literal without any escaping, allowing an attacker who can create or modify a video to inject arbitrary JavaScript that executes in the browser of any user who visits the affected download page. Version 26.0 fixes the issue.
CVSS 5.4
CVE-2026-33296 WRITEUP MEDIUM WRITEUP
AVideo has an Open Redirect via Unvalidated redirectUri in userLogin.php
WWBN AVideo is an open source video platform. Prior to version 26.0, WWBN/AVideo contains an open redirect vulnerability in the login flow where a user-supplied redirectUri parameter is reflected directly into a JavaScript `document.location` assignment without JavaScript-safe encoding. After a user completes the login popup flow, a timer callback executes the redirect using the unvalidated value, sending the victim to an attacker-controlled site. Version 26.0 fixes the issue.
CVSS 6.1
CVE-2026-33319 WRITEUP MEDIUM WRITEUP
AVideo Vulnerable to OS Command Injection via Unescaped URL in LinkedIn Video Upload Shell Command
WWBN AVideo is an open source video platform. Prior to version 26.0, the `uploadVideoToLinkedIn()` method in the SocialMediaPublisher plugin constructs a shell command by directly interpolating an upload URL received from LinkedIn's API response, without sanitization via `escapeshellarg()`. If an attacker can influence the LinkedIn API response (via MITM, compromised OAuth token, or API compromise), they can inject arbitrary OS commands that execute as the web server user. Version 26.0 contains a fix for the issue.
CVSS 5.9
CVE-2026-33237 WRITEUP MEDIUM WRITEUP
AVideo has SSRF in Scheduler Plugin via callbackURL Missing `isSSRFSafeURL()` Validation
WWBN AVideo is an open source video platform. Prior to version 26.0, the Scheduler plugin's `run()` function in `plugin/Scheduler/Scheduler.php` calls `url_get_contents()` with an admin-configurable `callbackURL` that is validated only by `isValidURL()` (URL format check). Unlike other AVideo endpoints that were recently patched for SSRF (GHSA-9x67-f2v7-63rw, GHSA-h39h-7cvg-q7j6), the Scheduler's callback URL is never passed through `isSSRFSafeURL()`, which blocks requests to RFC-1918 private addresses, loopback, and cloud metadata endpoints. An admin can configure a scheduled task with an internal network `callbackURL` to perform SSRF against cloud infrastructure metadata services or internal APIs not otherwise reachable from the internet. Version 26.0 contains a patch for the issue.
CVSS 5.5
