Backend information disclosure via malformed session cookie
Published Nov 20, 2025 · Updated Nov 20, 2025
Error-message information disclosure in LimeSurvey 6.13.0 allows remote attackers to read backend details via a malformed session cookie. The session-handling error path returns a raw Yii database exception instead of a generic response, revealing the database engine, lime_sessions table, keys, and conflicting content. No authentication or user interaction is required, but the reported consequence is limited to disclosure of application architecture and error context.
