OpenClaw's MSTeams attachment redirect handling could bypass configured media host allowlists

CVE-2026-32037GHSA-w76h-8m22-hpgh

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (openclaw 2026.2.22), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Summary In OpenClaw MSTeams media download flows, redirect handling could bypass configured mediaAllowHosts checks in specific attachment paths. Redirect chains were not consistently constrained to allowlisted targets before accepting fetched content. Affected Packages / Versions - Package: openclaw (npm) - Affected versions: <= 2026.2.21-2 (latest published at triage time) - Fixed in: 2026.2.22 (planned next release) Impact Attackers able to supply or influence attachment URLs could force redirect chains to non-allowlisted targets, weakening SSRF boundary controls for MSTeams media ingestion. Fix Commit(s) - 73d93dee64127a26f1acd09d0403b794cdeb4f5c - b34097f62df9d1960cc22600269cd3f3284e2124 Release Process Note patchedversions is pre-set to the planned next release (2026.2.22). Once that npm release is published, this advisory can be published without further version-field edits. OpenClaw thanks @tdjackey for reporting.

# Patch Next advisory brief: CVE-2026-32037

Advisory: OpenClaw's MSTeams attachment redirect handling could bypass configured media host allowlists
IDs: CVE-2026-32037, GHSA-w76h-8m22-hpgh
Record: https://patchnext.com/advisories/cve-2026-32037 (revision 3, source checked 26 Oct 2026, 12:46 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: openclaw 2026.2.22. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm openclaw: affected < 2026.2.22; fixed in 2026.2.22

## Suggested inspection (read-only)
- `npm ls openclaw --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on openclaw.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://osv.dev/vulnerability/GHSA-w76h-8m22-hpgh (OSV record GHSA-w76h-8m22-hpgh lists affected ranges: npm openclaw >=0 <2026.2.22 (fixed))
- Verified: https://github.com/advisories/GHSA-w76h-8m22-hpgh (GitHub-reviewed advisory GHSA-w76h-8m22-hpgh lists affected ranges: npm openclaw >=0 <2026.2.22)
