Silverstripe Framework has a Cross-site Scripting vulnerability with encoded payload

CVE-2024-32981GHSA-chx7-9x8h-r5mg

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (silverstripe/framework 5.2.16), 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.

Impact A bad actor with access to edit content in the CMS could send a specifically crafted encoded payload to the server, which could be used to inject a JavaScript payload on the front end of the site. The payload would be sanitised on the client-side, but server-side sanitisation doesn't catch it. The server-side sanitisation logic has been updated to sanitise against this type of attack.

# Patch Next advisory brief: CVE-2024-32981

Advisory: Silverstripe Framework has a Cross-site Scripting vulnerability with encoded payload
IDs: CVE-2024-32981, GHSA-chx7-9x8h-r5mg
Record: https://patchnext.com/advisories/cve-2024-32981 (revision 1, source checked 26 Oct 2026, 14:25 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: silverstripe/framework 5.2.16. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist silverstripe/framework: affected < 5.2.16; fixed in 5.2.16

## Suggested inspection (read-only)
- Packagist silverstripe/framework: 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/framework.
- 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-chx7-9x8h-r5mg (GitHub-reviewed advisory GHSA-chx7-9x8h-r5mg lists affected ranges: Packagist silverstripe/framework >=0 <5.2.16)
