CVE-2026-33650 WRITEUP HIGH
AVideo's Video Moderator Privilege Escalation via Ownership Transfer Enables Arbitrary Video Deletion
WWBN AVideo is an open source video platform. In versions up to and including 26.0, a user with the "Videos Moderator" permission can escalate privileges to perform full video management operations — including ownership transfer and deletion of any video — despite the permission being documented as only allowing video publicity changes (Active, Inactive, Unlisted). The root cause is that `Permissions::canModerateVideos()` is used as an authorization gate for full video editing in `videoAddNew.json.php`, while `videoDelete.json.php` only checks ownership, creating an asymmetric authorization boundary exploitable via a two-step ownership-transfer-then-delete chain. Commit 838e16818c793779406ecbf34ebaeba9830e33f8 contains a patch.
CVSS 7.6
CVE-2026-33651 WRITEUP HIGH
AVideo <=26.0 Live Schedule Reminder - Blind SQL Injection
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `remindMe.json.php` endpoint passes `$_REQUEST['live_schedule_id']` through multiple functions without sanitization until it reaches `Scheduler_commands::getAllActiveOrToRepeat()`, which directly concatenates it into a SQL `LIKE` clause. Although intermediate functions (`new Live_schedule()`, `getUsers_idOrCompany()`) apply `intval()` internally, they do so on local copies within `ObjectYPT::getFromDb()`, leaving the original tainted variable unchanged. Any authenticated user can perform time-based blind SQL injection to extract arbitrary database contents. Commit 75d45780728294ededa1e3f842f95295d3e7d144 contains a patch.
CVSS 8.1
CVE-2026-33668 WRITEUP HIGH
Vikunja Allows Disabled/Locked User Accounts to Authenticate via API Tokens, CalDAV, and OpenID Connect
Vikunja is an open-source self-hosted task management platform. Starting in version 0.18.0 and prior to version 2.2.1, when a user account is disabled or locked, the status check is only enforced on the local login and JWT token refresh paths. Three other authentication paths — API tokens, CalDAV basic auth, and OpenID Connect — do not verify user status, allowing disabled or locked users to continue accessing the API and syncing data. Version 2.2.1 patches the issue.
CVSS 8.1
CVE-2026-33675 WRITEUP MEDIUM
Vikunja has SSRF via Todoist/Trello Migration File Attachment URLs that Allows Reading Internal Network Resources
Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.1, the migration helper functions `DownloadFile` and `DownloadFileWithHeaders` in `pkg/modules/migration/helpers.go` make arbitrary HTTP GET requests without any SSRF protection. When a user triggers a Todoist or Trello migration, file attachment URLs from the third-party API response are passed directly to these functions, allowing an attacker to force the Vikunja server to fetch internal network resources and return the response as a downloadable task attachment. Version 2.2.1 patches the issue.
CVSS 6.4
CVE-2026-33676 WRITEUP MEDIUM
Vikunja has Cross-Project Information Disclosure via Task Relations — Missing Authorization Check on Related Task Read
Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.1, when the Vikunja API returns tasks, it populates the `related_tasks` field with full task objects for all related tasks without checking whether the requesting user has read permission on those tasks' projects. An authenticated user who can read a task that has cross-project relations will receive full details (title, description, due dates, priority, percent completion, project ID, etc.) of tasks in projects they have no access to. Version 2.2.1 patches the issue.
CVSS 6.5
CVE-2026-33679 WRITEUP MEDIUM
Vikunja has SSRF via OpenID Connect Avatar Download that Bypasses Webhook SSRF Protections
Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.1, the `DownloadImage` function in `pkg/utils/avatar.go` uses a bare `http.Client{}` with no SSRF protection when downloading user avatar images from the OpenID Connect `picture` claim URL. An attacker who controls their OIDC profile picture URL can force the Vikunja server to make HTTP GET requests to arbitrary internal or cloud metadata endpoints. This bypasses the SSRF protections that are correctly applied to the webhook system. Version 2.2.1 patches the issue.
CVSS 6.4
CVE-2026-33680 WRITEUP HIGH
Vikunja Vulnerable to Link Share Hash Disclosure via ReadAll Endpoint Enables Permission Escalation
Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.2, the `LinkSharing.ReadAll()` method allows link share authenticated users to list all link shares for a project, including their secret hashes. While `LinkSharing.CanRead()` correctly blocks link share users from reading individual shares via `ReadOne`, the `ReadAllWeb` handler bypasses this check by never calling `CanRead()`. An attacker with a read-only link share can retrieve hashes for write or admin link shares on the same project and authenticate with them, escalating to full admin access. Version 2.2.2 patches the issue.
CVSS 7.5
CVE-2026-33681 WRITEUP HIGH
AVideo has Path Traversal in pluginRunDatabaseScript.json.php Enables Arbitrary SQL File Execution via Unsanitized Plugin Name
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `objects/pluginRunDatabaseScript.json.php` endpoint accepts a `name` parameter via POST and passes it to `Plugin::getDatabaseFileName()` without any path traversal sanitization. This allows an authenticated admin (or an attacker via CSRF) to traverse outside the plugin directory and execute the contents of any `install/install.sql` file on the filesystem as raw SQL queries against the application database. Commit 81b591c509835505cb9f298aa1162ac64c4152cb contains a patch.
CVSS 7.2
CVE-2026-33685 WRITEUP MEDIUM
AVideo Allows Unauthenticated Access to AD_Server reports.json.php that Exposes Ad Campaign Analytics and User Data
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `plugin/AD_Server/reports.json.php` endpoint performs no authentication or authorization checks, allowing any unauthenticated attacker to extract ad campaign analytics data including video titles, user channel names, user IDs, ad campaign names, and impression/click counts. The HTML counterpart (`reports.php`) and CSV export (`getCSV.php`) both correctly enforce `User::isAdmin()`, but the JSON API was left unprotected. Commit daca4ffb1ce19643eecaa044362c41ac2ce45dde contains a patch.
CVSS 5.3
CVE-2026-33688 WRITEUP MEDIUM
AVideo has Pre-Captcha User Enumeration and Account Status Disclosure in Password Recovery Endpoint
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the password recovery endpoint at `objects/userRecoverPass.php` performs user existence and account status checks before validating the captcha. This allows an unauthenticated attacker to enumerate valid usernames and determine whether accounts are active, inactive, or banned — at scale and without solving any captcha — by observing three distinct JSON error responses. Commit e42f54123b460fd1b2ee01f2ce3d4a386e88d157 contains a patch.
CVSS 5.3
CVE-2026-33716 WRITEUP CRITICAL
AVideo Allows Unauthenticated Live Stream Control via Token Verification URL Override in control.json.php
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the standalone live stream control endpoint at `plugin/Live/standAloneFiles/control.json.php` accepts a user-supplied `streamerURL` parameter that overrides where the server sends token verification requests. An attacker can redirect token verification to a server they control that always returns `{"error": false}`, completely bypassing authentication. This grants unauthenticated control over any live stream on the platform, including dropping active publishers, starting/stopping recordings, and probing stream existence. Commit 388fcd57dbd16f6cb3ebcdf1d08cf2b929941128 contains a patch.
CVSS 9.4
CVE-2026-33717 WRITEUP HIGH
AVideo Vulnerable to Remote Code Execution via Persistent PHP Temp File in Encoder downloadURL with Resolution Validation Abort
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `downloadVideoFromDownloadURL()` function in `objects/aVideoEncoder.json.php` saves remote content to a web-accessible temporary directory using the original URL's filename and extension (including `.php`). By providing an invalid `resolution` parameter, an attacker triggers an early `die()` via `forbiddenPage()` before the temp file can be moved or cleaned up, leaving an executable PHP file persistently accessible under the web root at `videos/cache/tmpFile/`. Commit 6da79b43484099a0b660d1544a63c07b633ed3a2 contains a patch.
CVSS 8.8
CVE-2026-33723 WRITEUP HIGH
AVideo Vulnerable to SQL Injection in Subscribe Endpoint via Unsanitized user_id Parameter in subscribe.php
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `Subscribe::save()` method in `objects/subscribe.php` concatenates the `$this->users_id` property directly into an INSERT SQL query without sanitization or parameterized binding. This property originates from `$_POST['user_id']` in both `subscribe.json.php` and `subscribeNotify.json.php`. An authenticated attacker can inject arbitrary SQL to extract sensitive data from any database table, including password hashes, API keys, and encryption salts. Commit 36dfae22059fbd66fd34bbc5568a838fc0efd66c contains a patch.

CVSS 6.5
CVE-2026-26209 WRITEUP HIGH
cbor2 < 5.9.0 - Denial of Service via Deeply Nested CBOR Structures
cbor2 provides encoding and decoding for the Concise Binary Object Representation (CBOR) serialization format. Versions prior to 5.9.0 are vulnerable to a Denial of Service (DoS) attack caused by uncontrolled recursion when decoding deeply nested CBOR structures. This vulnerability affects both the pure Python implementation and the C extension `_cbor2`. The C extension relies on Python's internal recursion limits `Py_EnterRecursiveCall` rather than a data-driven depth limit, meaning it still raises `RecursionError` and crashes the worker process when the limit is hit. While the library handles moderate nesting levels, it lacks a hard depth limit. An attacker can supply a crafted CBOR payload containing approximately 100,000 nested arrays `0x81`. When `cbor2.loads()` attempts to parse this, it hits the Python interpreter's maximum recursion depth or exhausts the stack, causing the process to crash with a `RecursionError`. Because the library does not enforce its own limits, it allows an external attacker to exhaust the host application's stack resource. In many web application servers (e.g., Gunicorn, Uvicorn) or task queues (Celery), an unhandled `RecursionError` terminates the worker process immediately. By sending a stream of these small (<100KB) malicious packets, an attacker can repeatedly crash worker processes, resulting in a complete Denial of Service for the application. Version 5.9.0 patches the issue.
CVSS 7.5
CVE-2026-27646 WRITEUP MEDIUM
OpenClaw <2026.3.7 - Sandbox Escape
OpenClaw versions prior to 2026.3.7 contain a sandbox escape vulnerability in the /acp spawn command that allows authorized sandboxed sessions to initialize host-side ACP runtime. Attackers can bypass sandbox restrictions by invoking the /acp spawn slash-command to cross from sandboxed chat context into host-side ACP session initialization when ACP is enabled.
