OpenClaw validates Zalo outbound photo URLs through the SSRF guard

CVE-2026-44116GHSA-2hh7-c75g-qj2r

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (openclaw 2026.4.22), 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 Zalo outbound photo URLs are validated through the SSRF guard. Affected Packages / Versions - Package: openclaw (npm) - Affected versions: <= 2026.4.21 - Fixed version: 2026.4.22 Impact The Zalo plugin could forward an attacker-controlled outbound photo URL to the Zalo Bot API without first applying OpenClaw's SSRF validation policy. Fix Zalo sendPhoto now parses and validates outbound photo URLs with the shared SSRF hostname policy before posting to Zalo, and media-reply paths route through the guarded outbound media helpers. Fix Commit(s) - a65eb1b864b7630c1242a82de9e5799b80583c3f Verification - The fix commit is contained in the public v2026.4.22 tag. - openclaw@2026.4.22 is published on npm and the compiled package contains the fix. - Focused regression coverage for this path passed before publication. OpenClaw thanks @foodlook for reporting.

# Patch Next advisory brief: CVE-2026-44116

Advisory: OpenClaw validates Zalo outbound photo URLs through the SSRF guard
IDs: CVE-2026-44116, GHSA-2hh7-c75g-qj2r
Record: https://patchnext.com/advisories/cve-2026-44116 (revision 3, source checked 26 Oct 2026, 12:51 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: openclaw 2026.4.22. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm openclaw: affected <= 2026.4.21; fixed in 2026.4.22

## 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-2hh7-c75g-qj2r (OSV record GHSA-2hh7-c75g-qj2r lists affected ranges: npm openclaw >=0 <2026.4.22 (fixed))
- Verified: https://github.com/advisories/GHSA-2hh7-c75g-qj2r (GitHub-reviewed advisory GHSA-2hh7-c75g-qj2r lists affected ranges: npm openclaw >=0 <=2026.4.21)
