What is CVE-2026-92579?
CVE-2026-92579 is a medium-severity vulnerability in WWBN AVideo, published on 16 Sep 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
In AVideo through 29.0, the autoCSRFGuard() function maintains a hardcoded allowlist of exempt basenames tested without directory context, allowing plugin files matching core filenames to inherit CSRF exemptions. The LoginWordPress plugin file login.json.php inherits an exemption and unconditionally logs out authenticated users on cross-site POST requests before validating credentials.
