Summary
AVideo CVE-2026-43881 incomplete fix - `objects/mention.json.php:17` is an unauthenticated user enumeration sibling that survives `d9cdc7024`
Details

CVE-2026-43881 fix d9cdc7024 patched users.json.php only. The same anti-pattern survives at master HEAD in:

objects/mention.json.php:17     $ignoreAdmin = true;
objects/mention.json.php:18     $users = User::getAllUsers($ignoreAdmin,
                                    ['name', 'email', 'user', 'channelName'], 'a');

No User::loginCheck(), no admin gate. Only entry guard: preg_match('/^@/', $_REQUEST['term']) and hard-coded rowCount=10.

Severity
5.3 (Medium)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
