Authenticated session metadata modification via delimiter injection
Published Jun 1, 2026 · Updated Jun 1, 2026
Improper authorization in AstrBot 4.24.2 allows remote authenticated users to alter another user's session metadata via a session ID. The astr_main_agent path takes the substring after the final exclamation mark in attacker-controlled event.session_id and uses it to select and update a database session without verifying ownership. Dashboard authentication and knowledge or enumeration of a victim session identifier are required; the demonstrated consequence is unauthorized renaming of that session's display name.
