CVE-2026-58205
highGRR is a resource management and reservation application.
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.
