CVE-2026-47234Public exploitHinoki check available

Session hijacking via plaintext credential logging

Published Aug 12, 2026 · Updated Aug 12, 2026

Information disclosure in Admidio before 5.0.10 allows local users with log access to recover live session credentials. Session::setCookie() records full cookie values and Session::start() records the current session identifier in the application log instead of redacting bearer credentials. Debug logging and access to the configured log sink are required; exposed session and persistent auto-login cookies enable session hijacking and long-lived account access.
