Packages
Details
As written in the advisory (Markdown source, shown as plain text).
## Summary
MS Teams webhook parses body before JWT validation, enabling unauthenticated resource exhaustion
## Current Maintainer Triage
- Status: open
- Normalized severity: medium
- Assessment: v2026.3.28 still parses Teams JSON after only a Bearer-prefix gate and before real JWT validation, and the auth-before-parse fix is not yet shipped.
## Affected Packages / Versions
- Package: `openclaw` (npm)
- Latest published npm version: `2026.3.31`
- Vulnerable version range: `<=2026.3.28`
- Patched versions: `>= 2026.3.31`
- First stable tag containing the fix: `v2026.3.31`
