In versions 29.0 and prior, multiple AVideo JSON endpoints under `objects/` accept state-changing requests via `$_REQUEST`/`$_GET` and persist changes tied to the caller's session user, without any anti-CSRF token, origin check, or referer check. A malicious page visited by a logged-in victim can silently cast/flip the victim's like/dislike on any comment (`objects/comments_like.json.php`), post a comment authored by the victim on any video, with attacker-chosen text (`objects/commentAddNew.json.php`), and/or delete assets from any category (`objects/categoryDeleteAssets.json.php`) when the victim has category management rights. Each endpoint is reachable from a browser via a simple `<img src=\"…\">` tag or form submission, so exploitation only requires the victim to load an attacker-controlled HTML resource. Commit 7aaad601bd9cd7b993ba0ee1b1bea6c32ee7b77c contains a fix."}],"source":{"advisory":"GHSA-x2pw-9c38-cp2j","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-x2pw-9c38-cp2j","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-04-22T13:15:40.914548Z","id":"CVE-2026-40928","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-04-22T13:15:43.678Z"}}]}}
