Description
WWBN AVideo 6.5 through 29.7.1 contains an authentication bypass vulnerability that allows unauthenticated attackers to log in as any user via Hybridauth social login display names. Attackers can set their X, Facebook, Yahoo or LinkedIn display name to a victim's username and withhold email, causing login.json.php or oauth2.php to log them in as that account, including administrators, without a password.
Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Remediation status
The records we use list no fixed release for CVE-2026-126542. Check the upstream advisory for a patched version, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
