CVE-2026-41060 WRITEUP HIGH
AVideo's SSRF via same-domain hostname with alternate port bypasses isSSRFSafeURL
WWBN AVideo is an open source video platform. In versions 29.0 and below, the `isSSRFSafeURL()` function in `objects/functions.php` contains a same-domain shortcircuit (lines 4290-4296) that allows any URL whose hostname matches `webSiteRootURL` to bypass all SSRF protections. Because the check compares only the hostname and ignores the port, an attacker can reach arbitrary ports on the AVideo server by using the site's public hostname with a non-standard port. The response body is saved to a web-accessible path, enabling full exfiltration. Commit a0156a6398362086390d949190f9d52a823000ba fixes the issue.
CVSS 7.7
CVE-2026-41058 WRITEUP HIGH
AVideo <=29.0 CloneSite deleteDump - Path Traversal
WWBN AVideo is an open source video platform. In versions 29.0 and below, the incomplete fix for AVideo's CloneSite `deleteDump` parameter does not apply path traversal filtering, allowing `unlink()` of arbitrary files via `../../` sequences in the GET parameter. Commit 3c729717c26f160014a5c86b0b6accdbd613e7b2 contains an updated fix.

CVE-2026-41057 WRITEUP HIGH
AVideo has CORS Origin Reflection Bypass via plugin/API/router.php and allowOrigin(true) that Exposes Authenticated API Responses
WWBN AVideo is an open source video platform. In versions 29.0 and below, the CORS origin validation fix in commit `986e64aad` is incomplete. Two separate code paths still reflect arbitrary `Origin` headers with credentials allowed for all `/api/*` endpoints: (1) `plugin/API/router.php` lines 4-8 unconditionally reflect any origin before application code runs, and (2) `allowOrigin(true)` called by `get.json.php` and `set.json.php` reflects any origin with `Access-Control-Allow-Credentials: true`. An attacker can make cross-origin credentialed requests to any API endpoint and read authenticated responses containing user PII, email, admin status, and session-sensitive data. Commit 5e2b897ccac61eb6daca2dee4a6be3c4c2d93e13 contains a fix.
CVSS 7.1
CVE-2026-41056 WRITEUP HIGH
AVideos has CORS Origin Reflection with Credentials on Sensitive API Endpoints that Enables Cross-Origin Account Takeover
WWBN AVideo is an open source video platform. In versions 29.0 and below, the `allowOrigin($allowAll=true)` function in `objects/functions.php` reflects any arbitrary `Origin` header back in `Access-Control-Allow-Origin` along with `Access-Control-Allow-Credentials: true`. This function is called by both `plugin/API/get.json.php` and `plugin/API/set.json.php` — the primary API endpoints that handle user data retrieval, authentication, livestream credentials, and state-changing operations. Combined with the application's `SameSite=None` session cookie policy, any website can make credentialed cross-origin requests and read authenticated API responses, enabling theft of user PII, livestream keys, and performing state changes on behalf of the victim. Commit caf705f38eae0ccfac4c3af1587781355d24495e contains a fix.
CVSS 8.1
CVE-2026-41055 WRITEUP HIGH
WWBN AVideo LiveLinks Proxy - Server-Side Request Forgery
WWBN AVideo is an open source video platform. In versions 29.0 and below, an incomplete SSRF fix in AVideo's LiveLinks proxy adds `isSSRFSafeURL()` validation but leaves DNS TOCTOU vulnerabilities where DNS rebinding between validation and the actual HTTP request redirects traffic to internal endpoints. Commit 8d8fc0cadb425835b4861036d589abcea4d78ee8 contains an updated fix.

CVE-2026-40935 WRITEUP MEDIUM
WWBN/AVideo has CAPTCHA Bypass via Attacker-Controlled Length Parameter and Missing Token Invalidation on Failure
WWBN AVideo is an open source video platform. In versions 29.0 and prior, `objects/getCaptcha.php` accepts the CAPTCHA length (`ql`) directly from the query string with no clamping or sanitization, letting any unauthenticated client force the server to generate a 1-character CAPTCHA word. Combined with a case-insensitive `strcasecmp` comparison over a ~33-character alphabet and the fact that failed validations do NOT consume the stored session token, an attacker can trivially brute-force the CAPTCHA on any endpoint that relies on `Captcha::validation()` (user registration, password recovery, contact form, etc.) in at most ~33 requests per session. Commit bf1c76989e6a9054be4f0eb009d68f0f2464b453 contains a fix.
CVSS 5.3
CVE-2026-40929 WRITEUP MEDIUM
WWBN AVideo's missing CSRF protection in objects/commentDelete.json.php enables mass comment deletion against moderators and content creators
WWBN AVideo is an open source video platform. In versions 29.0 and prior, `objects/commentDelete.json.php` is a state-mutating JSON endpoint that deletes comments but performs no CSRF validation. It does not call `forbidIfIsUntrustedRequest()`, does not verify a CSRF/global token, and does not check `Origin`/`Referer`. Because AVideo intentionally sets `session.cookie_samesite=None` (to support cross-origin embed players), a cross-site request from any attacker-controlled page automatically carries the victim's `PHPSESSID`. Any authenticated victim who has authority to delete one or more comments (site moderators, video owners, and comment authors) can be tricked into deleting comments en masse simply by visiting an attacker page. Commit 184f36b1896f3364f864f17c1acca3dd8df3af27 contains a fix.
CVSS 5.4
CVE-2026-40928 WRITEUP MEDIUM
AVideo: Missing CSRF Protection on State-Changing JSON Endpoints Enables Forced Comment Creation, Vote Manipulation, and Category Asset Deletion
WWBN AVideo is an open source video platform. In versions 29.0 and prior, multiple AVideo JSON endpoints under `objects/` accept state-changing requests via `$_REQUEST`/`$_GET` and persist changes tied to the caller's session user, without any anti-CSRF token, origin check, or referer check. A malicious page visited by a logged-in victim can silently cast/flip the victim's like/dislike on any comment (`objects/comments_like.json.php`), post a comment authored by the victim on any video, with attacker-chosen text (`objects/commentAddNew.json.php`), and/or delete assets from any category (`objects/categoryDeleteAssets.json.php`) when the victim has category management rights. Each endpoint is reachable from a browser via a simple `<img src="…">` tag or form submission, so exploitation only requires the victim to load an attacker-controlled HTML resource. Commit 7aaad601bd9cd7b993ba0ee1b1bea6c32ee7b77c contains a fix.
CVSS 5.4
CVE-2026-40926 WRITEUP HIGH
WWBN AVideo Vulnerable to CSRF in Admin JSON Endpoints (Category CRUD, Plugin Update Script)
WWBN AVideo is an open source video platform. In versions 29.0 and prior, three admin-only JSON endpoints — `objects/categoryAddNew.json.php`, `objects/categoryDelete.json.php`, and `objects/pluginRunUpdateScript.json.php` — enforce only a role check (`Category::canCreateCategory()` / `User::isAdmin()`) and perform state-changing actions against the database without calling `isGlobalTokenValid()` or `forbidIfIsUntrustedRequest()`. Peer endpoints in the same directory (`pluginSwitch.json.php`, `pluginRunDatabaseScript.json.php`) do enforce the CSRF token, so the missing checks are an omission rather than a design choice. An attacker who lures a logged-in admin to a malicious page can create, update, or delete categories and force execution of any installed plugin's `updateScript()` method in the admin's session. Commit ee5615153c40628ab3ec6fe04962d1f92e67d3e2 contains a fix.
CVSS 7.1
CVE-2026-40925 WRITEUP HIGH
WWBN AVideo has CSRF in configurationUpdate.json.php Enables Full Site Configuration Takeover Including Encoder URL and SMTP Credentials
WWBN AVideo is an open source video platform. In versions 29.0 and prior, `objects/configurationUpdate.json.php` (also routed via `/updateConfig`) persists dozens of global site settings from `$_POST` but protects the endpoint only with `User::isAdmin()`. It does not call `forbidIfIsUntrustedRequest()`, does not verify a `globalToken`, and does not validate the Origin/Referer header. Because AVideo intentionally sets `session.cookie_samesite=None` to support cross-origin iframe embedding, a logged-in administrator who visits an attacker-controlled page will have the browser auto-submit a cross-origin POST that rewrites the site's encoder URL, SMTP credentials, site `<head>` HTML, logo, favicon, contact email, and more in a single request. Commit f9492f5e6123dff0292d5bb3164fde7665dc36b4 contains a fix.
CVSS 8.3
CVE-2026-40911 WRITEUP CRITICAL
WWBN AVideo YPTSocket WebSocket Broadcast Relay Leads to Unauthenticated Cross-User JavaScript Execution via Client-Side eval() Sinks
WWBN AVideo is an open source video platform. In versions 29.0 and prior, the YPTSocket plugin's WebSocket server relays attacker-supplied JSON message bodies to every connected client without sanitizing the `msg` or `callback` fields. On the client side, `plugin/YPTSocket/script.js` contains two `eval()` sinks fed directly by those relayed fields (`json.msg.autoEvalCodeOnHTML` at line 568 and `json.callback` at line 95). Because tokens are minted for anonymous visitors and never revalidated beyond decryption, an unauthenticated attacker can broadcast arbitrary JavaScript that executes in the origin of every currently-connected user (including administrators), resulting in universal account takeover, session theft, and privileged action execution. Commit c08694bf6264eb4decceb78c711baee2609b4efd contains a fix.
CVSS 10.0
CVE-2026-40909 WRITEUP HIGH
WWBN AVideo <= 29.0 - Path Traversal Remote Code Execution
WWBN AVideo is an open source video platform. In versions 29.0 and prior, the locale save endpoint (`locale/save.php`) constructs a file path by directly concatenating `$_POST['flag']` into the path at line 30 without any sanitization. The `$_POST['code']` parameter is then written verbatim to that path via `fwrite()` at line 40. An admin attacker (or any user who can CSRF an admin, since no CSRF token is checked and cookies use `SameSite=None`) can traverse out of the `locale/` directory and write arbitrary `.php` files to any writable location on the filesystem, achieving Remote Code Execution. Commit 57f89ffbc27d37c9d9dd727212334846e78ac21a fixes the issue.
CVSS 8.7
CVE-2026-40908 WRITEUP MEDIUM
AVideo <=29.0 git.json.php - Unauthenticated Information Disclosure
WWBN AVideo is an open source video platform. In versions 29.0 and prior, the file `git.json.php` at the web root executes `git log -1` and returns the full output as JSON to any unauthenticated user. This exposes the exact deployed commit hash (enabling version fingerprinting against known CVEs), developer names and email addresses (PII), and commit messages which may contain references to internal systems or security fixes. As of time of publication, no known patched versions are available.
CVSS 5.3
CVE-2026-40907 WRITEUP MEDIUM
WWBN AVideo has IDOR in Live Restreams list.json.php that Exposes Other Users' Stream Keys and OAuth Tokens
WWBN AVideo is an open source video platform. In versions 29.0 and prior, the endpoint `plugin/Live/view/Live_restreams/list.json.php` contains an Insecure Direct Object Reference (IDOR) vulnerability that allows any authenticated user with streaming permission to retrieve other users' live restream configurations, including third-party platform stream keys and OAuth tokens (access_token, refresh_token) for services like YouTube Live, Facebook Live, and Twitch. Commit d5992fff2811df4adad1d9fc7d0a5837b882aed7 fixes the issue.
CVSS 6.5
CVE-2026-39370 WRITEUP HIGH
WWBN AVideo <= 26.0 - Server-Side Request Forgery Response Exfiltration
WWBN AVideo is an open source video platform. In versions 26.0 and prior, objects/aVideoEncoder.json.php still allows attacker-controlled downloadURL values with common media or archive extensions such as .mp4, .mp3, .zip, .jpg, .png, .gif, and .webm to bypass SSRF validation. The server then fetches the response and stores it as media content. This allows an authenticated uploader to turn the upload-by-URL flow into a reliable SSRF response-exfiltration primitive. The vulnerability is caused by an incomplete fix for CVE-2026-27732.
CVSS 7.1
CVE-2026-39369 WRITEUP HIGH
WWBN AVideo's GIF poster fetch bypasses traversal scrubbing and exposes local files through public media URLs
WWBN AVideo is an open source video platform. In versions 26.0 and prior, objects/aVideoEncoderReceiveImage.json.php allowed an authenticated uploader to fetch attacker-controlled same-origin /videos/... URLs, bypass traversal scrubbing, and expose server-local files through the GIF poster storage path. The vulnerable GIF branch could be abused to read local files such as /etc/passwd or application source files and republish those bytes through a normal public GIF media URL.
CVSS 7.6
CVE-2026-39368 WRITEUP MEDIUM
AVideo <=26.0 Live Restream Callback - Stored Server-Side Request Forgery
WWBN AVideo is an open source video platform. In versions 26.0 and prior, the Live restream log callback flow accepted an attacker-controlled restreamerURL and later fetched that stored URL server-side, enabling stored SSRF for authenticated streamers. The vulnerable flow allowed a low-privilege user with streaming permission to store an arbitrary callback URL and trigger server-side requests to loopback or internal HTTP services through the restream log feature.
CVSS 6.5
CVE-2026-39367 WRITEUP MEDIUM
WWBN AVideo has Stored XSS via Malicious EPG XML Program Titles in AVideo EPG Page
WWBN AVideo is an open source video platform. In versions 26.0 and prior, AVideo's EPG (Electronic Program Guide) feature parses XML from user-controlled URLs and renders programme titles directly into HTML without any sanitization or escaping. A user with upload permission can set a video's epg_link to a malicious XML file whose <title> elements contain JavaScript. This payload executes in the browser of any unauthenticated visitor to the public EPG page, enabling session hijacking and account takeover.
CVSS 5.4
CVE-2026-39366 WRITEUP MEDIUM
WWBN AVideo Affected by a PayPal IPN Replay Attack Enabling Wallet Balance Inflation via Missing Transaction Deduplication in ipn.php
WWBN AVideo is an open source video platform. In versions 26.0 and prior, the PayPal IPN v1 handler at plugin/PayPalYPT/ipn.php lacks transaction deduplication, allowing an attacker to replay a single legitimate IPN notification to repeatedly inflate their wallet balance and renew subscriptions. The newer ipnV2.php and webhook.php handlers correctly deduplicate via PayPalYPT_log entries, but the v1 handler was never updated and remains actively referenced as the notify_url for billing plans.
CVSS 6.5
CVE-2026-35452 WRITEUP MEDIUM
WWBN AVideo has Unauthenticated Information Disclosure via Missing Auth on CloneSite client.log.php
WWBN AVideo is an open source video platform. In versions 26.0 and prior, the plugin/CloneSite/client.log.php endpoint serves the clone operation log file without any authentication. Every other endpoint in the CloneSite plugin directory enforces User::isAdmin(). The log contains internal filesystem paths, remote server URLs, and SSH connection metadata.
CVSS 5.3
CVE-2026-35450 WRITEUP MEDIUM
WWBN AVideo has Unauthenticated FFmpeg Remote Server Status Disclosure via check.ffmpeg.json.php
WWBN AVideo is an open source video platform. In versions 26.0 and prior, the plugin/API/check.ffmpeg.json.php endpoint probes the FFmpeg remote server configuration and returns connectivity status without any authentication. All sibling FFmpeg management endpoints (kill.ffmpeg.json.php, list.ffmpeg.json.php, ffmpeg.php) require User::isAdmin().
CVSS 5.3
CVE-2026-35449 WRITEUP MEDIUM
WWBN AVideo has Unauthenticated Information Disclosure via Disabled CLI Guard in install/test.php
WWBN AVideo is an open source video platform. In versions 26.0 and prior, the install/test.php diagnostic script has its CLI-only access guard disabled by commenting out the die() statement. The script remains accessible via HTTP after installation, exposing video viewer statistics including IP addresses, session IDs, and user agents to unauthenticated visitors.
CVSS 5.3
CVE-2026-35448 WRITEUP LOW
WWBN AVideo Provides Unauthenticated Access to Payment Order Data via BlockonomicsYPT check.php
WWBN AVideo is an open source video platform. In versions 26.0 and prior, the BlockonomicsYPT plugin's check.php endpoint returns payment order data for any Bitcoin address without requiring authentication. The endpoint was designed as an AJAX polling helper for the authenticated invoice.php page, but it performs no access control checks of its own. Since Bitcoin addresses are publicly visible on the blockchain, an attacker can query payment records for any address used on the platform.
CVSS 3.7
