OpenClaw: Shared-secret comparison call sites leaked length information through timing

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...
