OpenClaw: Feishu webhook reads and parses unauthenticated request bodies before signature validation
Summary
Feishu webhook reads and parses unauthenticated request bodies before signature validation
Affected Packages / Versions
- Package:
openclaw - Affected versions:
<= 2026.3.24 - First patched version:
2026.3.25 - Latest published npm version at verification time:
2026.3.24
Details
Feishu webhook handling previously parsed JSON before signature validation, which let unauthenticated callers force full JSON parsing work before rejection. Commit 5e8cb22176e9235e224be0bc530699261eb60e53 reads the raw request body, validates the signature first, and only then parses JSON.
Verified vulnerable on tag v2026.3.24 and fixed on main by commit 5e8cb22176e9235e224be0bc530699261eb60e53.

Связанные уязвимости
OpenClaw before 2026.3.25 parses JSON request bodies before validating webhook signatures, allowing unauthenticated attackers to force resource-intensive parsing operations. Remote attackers can send malicious webhook requests to trigger denial of service by exhausting server resources through forced JSON parsing before signature rejection.
