About Wwbn Avideo-Encoder
CVE-2026-33024 affects Wwbn Avideo-Encoder, a product from Wwbn. Before acting, confirm where Wwbn Avideo-Encoder runs in your estate, who owns it and whether it is reachable from the internet, because exposure decides real risk more than the score alone.
What the flaw is
In plain terms: AVideo is a video-sharing Platform. Versions prior to 8.0 contain a Server-Side Request Forgery vulnerability (CWE-918) in the public thumbnail endpoints getImage.php and getImageMP4.php. Both endpoints accept a base64Url GET parameter, base64-decode it, and pass the resulting URL to ffmpeg as an input source without any authentication requirement. The prior validation only checked that the URL was syntactically valid (FILTER_VALIDATE_URL) and started with http(s)://. This is insufficient: an attacker can supply URLs such as http://169.254.169.254/latest/meta-data/ (AWS/cloud instance metadata), http://192.168.x.x/, or http://127.0.0.1/ to make the server reach internal network resources. The response is not directly returned (blind), but timing differences and error logs can be used to infer results. The issue has been fixed in version 8.0.
The weakness class is Server Side Request Forgery. The server can be made to send requests to internal or arbitrary systems.
Based on its CVSS vector, the flaw can be reached over the network, needs no login, and needs no user interaction. Apply the vendor fix and confirm exposure on internet facing and business critical assets first.

How to detect it
- Inventory every instance of Wwbn Avideo-Encoder and record the running version against the affected range above.
- Check external attack surface scans for internet facing instances of the component.
- Review logs on affected systems for unusual requests, errors or new processes around the vulnerable function.
- Confirm with an authenticated vulnerability scan once your scanner has a check for this CVE.
How to fix it
- Apply the fixed version of Wwbn Avideo-Encoder named in the vendor advisory.
- If patching must wait, restrict network access to the affected service and put it behind authentication or a web application firewall rule.
- Rescan after the change to prove the exposure is gone, then close the ticket.
CTEM action plan
| CTEM stage | What to do for this CVE |
|---|---|
| Scope | Add every business service that depends on Wwbn Avideo-Encoder to the current CTEM cycle. |
| Discover | Find all instances, including shadow and cloud deployments, and record versions and exposure. |
| Prioritize | Rank using EPSS and CVSS together with asset exposure and business impact. |
| Validate | Confirm the flaw is reachable and exploitable in your environment and that compensating controls work. |
| Mobilize | Assign the fix to the asset owner with a due date matched to the priority, then verify closure. |

WWBN AVideo is an open source video platform. In versions 29.0 and below, the `cloneServer.json.php` endpoint in the CloneSite plugin constructs shell commands using user-controlled input (`url` parameter) without proper sanitization. The input is directly concatenated into a `wget` command executed via `exec()`, allowing command injection. An attacker can inject arbitrary shell commands by breaking out of the intended URL context using shell metacharacters (e.g., `;`). This leads to Remote Code Execution (RCE) on the server. Commit 473c609fc2defdea8b937b00e86ce88eba1f15bb contains a fix.
WWBN AVideo is an open source video platform. In versions up to and including 26.0, AVideo allows content owners to password-protect individual videos. The video password is stored in the database in plaintext — no hashing, salting, or encryption is applied. If an attacker gains read access to the database (via SQL injection, a database backup, or misconfigured access controls), they obtain all video passwords in cleartext. Commit f2d68d2adbf73588ea61be2b781d93120a819e36 contains a patch.
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `fixCleanTitle()` static method in `objects/category.php` constructs a SQL SELECT query by directly interpolating both `$clean_title` and `$id` into the query string without using prepared statements or parameterized queries. An attacker who can trigger category creation or renaming with a crafted title value can inject arbitrary SQL. Commit 994cc2b3d802b819e07e6088338e8bf4e484aae4 contains a patch.
WWBN AVideo is an open source video platform. In versions up to and including 26.0, in `objects/like.php`, the `getLike()` method constructs a SQL query using a prepared statement placeholder (`?`) for `users_id` but directly concatenates `$this->videos_id` into the query string without parameterization. An attacker who can control the `videos_id` value (via a crafted request) can inject arbitrary SQL, bypassing the partial prepared-statement protection. Commit 0215d3c4f1ee748b8880254967b51784b8ac4080 contains a patch.
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `remindMe.json.php` endpoint passes `$_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.
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `plugin/Permissions/setPermission.json.php` endpoint accepts GET parameters for a state-changing operation that modifies user group permissions. The endpoint has no CSRF token validation, and the application explicitly sets `session.cookie_samesite=None` on session cookies. This allows an unauthenticated attacker to craft a page with `<img>` tags that, when visited by an admin, silently grant arbitrary permissions to the attacker's user group — escalating the attacker to near-admin access. As of time of publication, no known patched versions are available.
