CVE-2026-28464

HighCVSS 7.5/10Last modified Jun 17, 2026

Description

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.
