CVE-2026-58205 Details
Description
GRR is a resource management and reservation application. Prior to version 4.5.0, `maj.php` reflects the `forcemaj` parameter without adequate escaping when installation files remain accessible. Removal of these files is not automatic. An attacker can craft a URL that executes arbitrary JavaScript in a victim's browser when the victim accesses it. This reflected cross-site scripting can enable phishing, redirection to malicious sites, cookie theft and session hijacking because the authentication cookie is not `HttpOnly`. This issue is fixed in version 4.5.0.
A reflected cross-site scripting vulnerability has been identified in the GRR resource management application, prior to version 4.5.0. The issue arises in the 'maj.php' file, which reflects the 'forcemaj' parameter without proper escaping, allowing attackers to inject arbitrary JavaScript. This vulnerability is present when installation files are not automatically removed and remain accessible. Exploitation can lead to phishing attacks, redirection to malicious sites, cookie theft, and session hijacking, as the authentication cookie is not set to 'HttpOnly'.
Users should update to GRR version 4.5.0 or later, and ensure that the 'personnalisation' folder is writable for customizations.
