CVE-2026-41407
|
| Summary | 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 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. ## Affected Packages / Versions - Package: `openclaw` (npm) - Affected versions: `<= 2026.4.1` - Patched versions: `>= 2026.4.2` - Latest published npm version: `2026.4.1` ## Fix Commit(s) - `be10ecef770a4654519869c3641bbb91087c8c7b` — reuse the shared secret comparison helper at affected call sites ## Release Process Note The fix is present on `main` and is staged for OpenClaw `2026.4.2`. Publish this advisory after the `2026.4.2` npm release is live. Thanks @kexinoh of Tencent zhuque Lab (https://github.com/Tencent/AI-Infra-Guard) for reporting. |
