How to Fix GHSA-25gq-jvx2-vg9x

To remediate this vulnerability, upgrade all affected Silverstripe/framework dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

silverstripe/framework fixed: 3.1.13 
Upgrade silverstripe/framework to 3.1.13
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

How to Check if You Are Affected

To determine whether your application is affected by GHSA-25gq-jvx2-vg9x, inspect your project dependencies for Silverstripe/framework:

inspect dependencies for silverstripe/framework

Analyze the terminal output to locate any version of Silverstripe/framework in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.1.13), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-601: URL Redirection to Untrusted Site ('Open Redirect'), where the web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect. In Silverstripe/framework, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A potential hostname injection vulnerability has been found which could allow attackers to alter url resolution. If a request contains the X-Forwarded-Host HTTP header a website would then use its value in place of the actual HTTP hostname. In cases where caching is enabled, this could allow an attacker to potentially embed a remote url as the base_url for any site. This would then cause other visitors to the site to be redirected unknowingly. This header is necessary for servers running behind a reverse proxy (such as nginx). Such servers are likely not vulnerable to this risk. A fix has been merged into the default installer, although existing projects which do not run behind a reverse proxy should update their htaccess as below: ``` <IfModule mod_headers.c> # Remove X-Forwarded-Host header sent as a part of any request from the web RequestHeader unset X-Forwarded-Host </IfModule> ```
