Sakura-501

**Name of the Vulnerable Software and Affected Versions** Piwigo version 13.4.0 **Description** A stored cross-site scripting (XSS) vulnerability in identification.php allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the `User-Agent`. This issue enables attackers to inject malicious code, potentially leading to unauthorized actions on the affected system. **Recommendations** For Piwigo version 13.4.0, as a temporary workaround, consider restricting access to the identification.php file until a patch is available. Avoid using the `User-Agent` header in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
