Summary
Silverstripe XSS in Director::force_redirect()
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.
Impact
Untrusted input is rendered as active markup in a victim's browser, which can run script in their session. Typical impact: session or credential theft, and actions taken as the user.
GHSA-JQP8-V74P-G8PX has a CVSS score of 6.1 (Medium). The vector is network-reachable, no privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (3.1.12); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is GHSA-JQP8-V74P-G8PX? GHSA-JQP8-V74P-G8PX is a medium-severity cross-site scripting (XSS) vulnerability in silverstripe/framework (composer), affecting versions >= 3.1.0, < 3.1.12. It is fixed in 3.1.12. Untrusted input is rendered as active markup in a victim's browser, which can run script in their session.
- How severe is GHSA-JQP8-V74P-G8PX? GHSA-JQP8-V74P-G8PX has a CVSS score of 6.1 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of silverstripe/framework are affected by GHSA-JQP8-V74P-G8PX? silverstripe/framework (composer) versions >= 3.1.0, < 3.1.12 is affected.
- Is there a fix for GHSA-JQP8-V74P-G8PX? Yes. GHSA-JQP8-V74P-G8PX is fixed in 3.1.12. Upgrade to this version or later.
- Is GHSA-JQP8-V74P-G8PX exploitable, and should I be worried? Whether GHSA-JQP8-V74P-G8PX is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether GHSA-JQP8-V74P-G8PX is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
