In versions 29.0 and prior, three admin-only JSON endpoints \u2014 `objects/categoryAddNew.json.php`, `objects/categoryDelete.json.php`, and `objects/pluginRunUpdateScript.json.php` \u2014 enforce only a role check (`Category::canCreateCategory()` / `User::isAdmin()`) and perform state-changing actions against the database without calling `isGlobalTokenValid()` or `forbidIfIsUntrustedRequest()`. Peer endpoints in the same directory (`pluginSwitch.json.php`, `pluginRunDatabaseScript.json.php`) do enforce the CSRF token, so the missing checks are an omission rather than a design choice. An attacker who lures a logged-in admin to a malicious page can create, update, or delete categories and force execution of any installed plugin's `updateScript()` method in the admin's session. Commit ee5615153c40628ab3ec6fe04962d1f92e67d3e2 contains a fix."}], "lastModified": "2026-06-17T10:45:53.773", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:wwbn:avideo:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "AC38CA07-71C1-4C86-B84A-83CF96367CBA", "versionEndIncluding": "29.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
