Overview
Affected versions of this package are vulnerable to Authorization Bypass Through User-Controlled Key via the monitor API endpoints, which lack proper ownership enforcement. An attacker can read, modify, rename, or permanently delete another user's messages, sessions, build artifacts, and transaction logs by supplying the target's resource ID or flow_id.
Note:* This is only exploitable if the attacker is an authenticated user and knows or can enumerate the target's resource identifiers.
