Name of the Vulnerable Software and Affected Versions OpenClaw versions prior to 2026.4.2

Description A timing side channel occurs in shared-secret comparison call sites that utilize early length-mismatch checks rather than fixed-length comparison helpers. This allows attackers to measure timing differences to leak information regarding the length of the secret, which weakens the constant-time handling of shared secrets.

Recommendations Update to version 2026.4.2.
