AI-suggested
Apply the official patches by upgrading to Stage File Proxy versions 3.1.7 or 4.0.1 or later. Avoid enabling the Stage File Proxy module on production sites, as it is intended only for development environments. No additional mitigation is required beyond patching and proper module usage.
Description
Stage File Proxy is a Drupal module designed to fetch production files on development servers. It is not intended for use on production sites. A vulnerability exists due to insufficient validation of file URLs during fallback retrieval, leading to a cross-site scripting (XSS) vulnerability. Exploitation requires the module to be enabled on the target site and the attacker to have the ability to upload a malicious file to the configured origin server. Fixed versions 3.1.7 and 4.0.1 address this issue.
