Summary
A flaw in AstrBot up to version 4.25.5 affects the OpenApiRoute.get_chat_sessions function in astrbot/dashboard/routes/open_api.py. Manipulation of the Username argument in the session-listing endpoint leads to authorization bypass. The attack is remotely exploitable and a public exploit exists.
Risk Assessment
The risk involves unauthorized access to chat sessions, potentially leading to leakage of sensitive user data or session hijacking. Remote exploitability increases the threat to the organization.
