Summary
Before OpenClaw 2026.4.2, several shared-secret comparison call sites still used early length-mismatch checks instead of the shared fixed-length comparison helper. Those paths could leak secret-length information through measurable timing differences.
Impact
The affected paths exposed a low-severity timing side channel on secret comparison. The issue did not by itself demonstrate auth bypass, but it weakened the intended constant-time handling for shared secrets.
