## 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`.
