## Summary

WWBN AVideo, versions in the affected range, contains a path traversal flaw in the ADs plugin's deleteImage.json.php script. A remote attacker with a low-privilege login, such as a user who has created custom ads, can abuse the unchecked is_regular_user parameter or ../ sequences to delete other users' ads or critical files like videos/configuration.php, which can take the site offline and re-expose the installer.

## Affected

- WWBN AVideo: from 12.4, through 29.7.1

## Description

WWBN AVideo 12.4 through 29.7.1 contains a path traversal vulnerability in the ADs plugin deleteImage.json.php that allows authenticated users with custom ads to delete arbitrary files. Attackers can set the unvalidated is_regular_user parameter to another user's id or ../ sequences to delete other users' ads or files like videos/configuration.php, taking the site offline and re-exposing the installer.

Check whether my systems are affected by CVE-2026-126804 (WWBN AVideo 12.4 through 29.7.1 Path Traversal File Deletion via deleteImage.json.php), using the cve.now data below.

Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.

What cve.now has for CVE-2026-126804 (entry last updated 2026-11-11):
Affected:
- WWBN AVideo: from 12.4, through 29.7.1
Fixed versions: none listed yet.
Conditions (all must be true for the bug to be hit):
- The ADs plugin must be enabled. (source: https://github.com/WWBN/AVideo/security/advisories/GHSA-58h3-9722-fgpm)
- The attacker must be a registered user whose account has the 'Can have custom ads' permission enabled. (source: https://github.com/WWBN/AVideo/security/advisories/GHSA-58h3-9722-fgpm)
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
Attacker needs: network access, low-privilege login, no user action.
Workaround: Disable the ADs plugin or revoke the custom ads permission from untrusted users until a verified fix is available. (source: https://github.com/WWBN/AVideo/security/advisories/GHSA-58h3-9722-fgpm)
CISA KEV: CVE-2026-126804 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-126804 only. If you also check another CVE, look up its own KEV status; never assume it from this one.

How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.

Verify against the linked advisories before concluding, and cite the date you read each one:

## FAQ

### Is CVE-2026-126804 being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.

Source: https://cve.now/CVE-2026-126804

### What does this mean?

A registered user with low privileges can use a path traversal flaw in deleteImage.json.php to delete other users' ads, the site-wide ads, and any web-server-writable file outside the ADs directory. Deleting files such as videos/configuration.php can take the site offline and re-expose the installer.
