# WWBN AVideo: path traversal in ADs plugin lets users delete arbitrary files

Link for people: https://infrastack.ai/live/CVE-2026-126804 (this .md is for agents)

AVideo's ADs plugin deleteImage.json.php does not validate the is_regular_user parameter or path sequences, so a logged-in user with custom ads can delete other users' ads or arbitrary files. Deleting videos/configuration.php takes the site offline and re-exposes the installer.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check whether the AVideo install runs the ADs plugin and whether the affected range (12.4 through 29.7.1) applies to your version
- Review the installed version in the AVideo admin panel or version file

## Fix

- Move to an AVideo version above 29.7.1 (fixed version not stated in the sources)

## From the sources

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.
