Updated under an hour ago ()

Does this affect you?

It affects OpenClaw. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

OpenClaw versions prior to 2026.2.12 use non-constant-time string comparison for hook token validation, allowing attackers to infer tokens through timing measurements. Remote attackers with network access to the hooks endpoint can exploit timing side-channels across multiple requests to gradually determine the authentication token.
