CVE-2022-38145GHSA-66jf-xm2m-7m8r

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (silverstripe/versioned-admin 1.11.1), 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.

A malicious content author could add a Javascript payload to a page's meta description and get it executed in the versioned history compare view. This vulnerability requires access to the CMS to be deployed. The attacker must then convince a privileged user to access the version history for that page.

# Patch Next advisory brief: CVE-2022-38145

Advisory: Stored XSS in Compare Mode
IDs: CVE-2022-38145, GHSA-66jf-xm2m-7m8r
Record: https://patchnext.com/advisories/cve-2022-38145 (revision 1, source checked 26 Oct 2026, 14:04 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.4)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: silverstripe/versioned-admin 1.11.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist silverstripe/versioned-admin: affected >= 1.0.0, < 1.11.1; fixed in 1.11.1

## Suggested inspection (read-only)
- Packagist silverstripe/versioned-admin: check the installed version with your package manager.

## 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 silverstripe/versioned-admin.
- 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://github.com/advisories/GHSA-66jf-xm2m-7m8r (GitHub-reviewed advisory GHSA-66jf-xm2m-7m8r lists affected ranges: Packagist silverstripe/versioned-admin >=1.0.0 <1.11.1)

Commands are suggestions: review each one before running it.
