NVD description
OpenClaw versions prior to 2026.2.14 contain an authorization bypass vulnerability where Telegram allowlist matching accepts mutable usernames instead of immutable numeric sender IDs. Attackers can spoof identity by obtaining recycled usernames to bypass allowlist restrictions and interact with bots as unauthorized senders.
What to do
- Upgrade OpenClaw to
2026.2.14or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
