CVE-2026-77753Network attack vectorHinoki check available

Authenticated access persistence via unreclaimed Application Passwords

Published Sep 12, 2026 · Updated Sep 12, 2026

Access-control bypass in StoreApps Temporary Login Without Password before 1.9.9 allows remote authenticated users to retain site access. Temporary-user expiration and deactivation paths leave WordPress Application Passwords intact instead of revoking them. A temporary user must first create an Application Password, which preserves the granted role over REST or XML-RPC after link access ends.
