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.

Read the original 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.

Who should check

Teams running WWBN AVideo 12.4 through 29.7.1 with the ADs plugin enabled and users granted custom ads rights

Check your systems with an agent

Paste this into a coding or ops agent. It checks your systems read-only and reports a table per asset.

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.

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:
- https://github.com/WWBN/AVideo/security/advisories/GHSA-58h3-9722-fgpm
- https://github.com/WWBN/AVideo/commit/c2b99663d6442e2182a0f3ab95ea6731a193b301

Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.

Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.

Questions about CVE-2026-126804

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: cve.now feed data

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.Source: github.com, vulncheck.com

Which versions are affected by CVE-2026-126804?

AVideo: from 12.4 through 29.7.1.Source: cve.now feed data

Am I affected, and how do I check?

Versions 12.4 through 29.7.1 of WWBN AVideo are in the affected range. The setup also requires the ADs plugin to be enabled and an account with the 'Can have custom ads' permission. To check, look at the plugin list in the admin panel for ADs and at the user permission settings for that permission.Source: github.com, vulncheck.com

How do I fix CVE-2026-126804?

No fixed version is listed in the checked facts, so no upgrade target can be given. Until a verified fix is available, disable the ADs plugin or revoke the custom ads permission from untrusted users.Source: github.com, vulncheck.com
