BREW-openclaw-cli-CVE-2026-32011 — OpenClaw has pre-auth webhook body parsing that can enable unauthenticated slow-request DoS

Affected: Homebrew: openclaw-cli

## Impact

OpenClaw webhook handlers for BlueBubbles and Google Chat accepted and parsed request bodies before authentication and signature checks on vulnerable releases. This allowed unauthenticated clients to hold parser work open with slow/oversized request bodies and degrade availability (slow-request DoS).

## Affected Packages / Versions

- Package: `openclaw` (npm) - Affected releases: `<= 2026.3.1` - Latest published vulnerable version at triage time: `2026.3.1` (npm) - Fixed release: `2026.3.2` (released)

## Fix Commit(s)

- `d3e8b17aa6432536806b4853edc7939d891d0f25`

## Mitigation

Upgrade to `2026.3.2` (or newer). The fix enforces auth-before-body for affected webhook paths, adds strict pre-auth body/time budgets, and introduces shared in-flight/request guardrails with regression coverage.

OpenClaw versions prior to 2026.3.2 contain a denial of service vulnerability in webhook handlers for BlueBubbles and Google Chat that parse request bodies before performing authentication and signature validation. Unauthenticated attackers can exploit this by sending slow or oversized request bodies to exhaust parser resources and degrade service availability.
