CVE-2026-41407: Openclaw

Medium severity, CVSS 5.3. EPSS: 0.4% chance of exploitation in the next 30 days.

OpenClaw before 2026.4.2 contains a timing side channel vulnerability in shared-secret comparison call sites that use early length-mismatch checks instead of fixed-length comparison helpers. Attackers can measure timing differences to leak secret-length information, weakening constant-time handling for shared secrets.
