CVE-2026-40929 Detail
Received
This CVE record has recently been published to the CVE List and has been included within the NVD dataset. DescriptionWWBN AVideo is an open source video platform. In versions 29.0 and prior, `objects/commentDelete.json.php` is a state-mutating JSON endpoint that deletes comments but performs no CSRF validation. It does not call `forbidIfIsUntrustedRequest()`, does not verify a CSRF/global token, and does not check `Origin`/`Referer`. Because AVideo intentionally sets `session.cookie_samesite=None` (to support cross-origin embed players), a cross-site request from any attacker-controlled page automatically carries the victim's `PHPSESSID`. Any authenticated victim who has authority to delete one or more comments (site moderators, video owners, and comment authors) can be tricked into deleting comments en masse simply by visiting an attacker page. Commit 184f36b1896f3364f864f17c1acca3dd8df3af27 contains a fix. Metrics
