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.
