Path Traversal in WWBN AVideo CloneSite Allows Arbitrary File Deletion

Publication date: 2026-04-21

Last updated on: 2026-04-24

Assigner: GitHub, Inc.

Description
WWBN AVideo is an open source video platform. In versions 29.0 and below, the incomplete fix for AVideo's CloneSite `deleteDump` parameter does not apply path traversal filtering, allowing `unlink()` of arbitrary files via `../../` sequences in the GET parameter. Commit 3c729717c26f160014a5c86b0b6accdbd613e7b2 contains an updated fix.

Executive Summary

This vulnerability exists in WWBN AVideo, an open source video platform, in versions 29.0 and below. It involves the CloneSite feature's `deleteDump` parameter, where an incomplete fix failed to properly filter path traversal sequences. This allows an attacker to use `../../` sequences in the GET parameter to perform an `unlink()` operation on arbitrary files, effectively deleting files outside the intended directory.

Impact Analysis

The vulnerability can lead to the deletion of arbitrary files on the server where WWBN AVideo is hosted. This can cause significant disruption, including loss of important data or system files, potentially leading to denial of service or impacting the integrity and availability of the platform.

Mitigation Strategies

To mitigate this vulnerability, update WWBN AVideo to a version that includes the fix for the CloneSite `deleteDump` parameter path traversal issue. Specifically, apply the fix contained in commit 3c729717c26f160014a5c86b0b6accdbd613e7b2 or later.
