Lifecycle Timeline
4Description
OpenClaw before 2026.3.25 contains an authorization bypass vulnerability in Telegram callback query handling that allows attackers to mutate session state without satisfying normal DM pairing requirements. Remote attackers can exploit weaker callback-only authorization in direct messages to bypass DM pairing and modify session state.
Analysis
OpenClaw before 2026.3.25 allows remote attackers to bypass Telegram direct message pairing requirements and mutate session state through weaker callback-only authorization mechanisms. An unauthenticated attacker can craft malicious Telegram callback queries in direct messages to modify session state without satisfying the normal DM pairing security controls, resulting in unauthorized state modification with CVSS 5.3 (medium severity).
