Description

A low level XSS vulnerability has been found in the Framework affecting http redirection via the Director::force_redirect method.

Attempts to redirect to a url may generate HTML which is not safely escaped, and may pose a risk of XSS in some environments.

This vulnerability is marked low as it is difficult to exploit, as any injected HTML will only be returned from the server if the Location HTTP header is also sent, meaning that any user browsing the site would not be exposed to the body of the response before their browser redirects them.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for silverstripe/framework, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update silverstripe/framework to 3.1.12 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-jqp8-v74p-g8px is resolved across your whole dependency graph.

  3. Workarounds

    Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
