Affected: OpenClaw

OpenClaw before 2026.3.31 parses MS Teams webhook request bodies before performing JWT validation, allowing unauthenticated attackers to trigger resource exhaustion. Remote attackers can send malicious Teams webhook payloads to exhaust server resources by bypassing authentication checks.

Affected: npm: openclaw

## 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`

## Fix Commit(s) - `3834d47099dd13c8244ed6de8b9ea9855c553623` — 2026-03-30T13:46:40+01:00
