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4.5.0.","severity":"high","score":8.1,"published":"2026-10-27T22:26:14.705Z","modified":"2026-10-27T22:26:14.705Z","withdrawn":false,"knownExploited":false,"affected":[],"references":["https://github.com/JeromeDevome/GRR/security/advisories/GHSA-r6x2-w38j-vvq2","https://github.com/JeromeDevome/GRR/commit/4ef77f91818215c1f8e0f06023d89257dfd61c68","https://github.com/JeromeDevome/GRR/tree/v4.5.0"],"sources":[{"name":"CVE","id":"CVE-2026-58205","modified":"2026-10-27T22:26:14.705Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-58205"}],"assessments":[{"source":"GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","score":8.1}],"sourceAffected":[],"kev":{"status":"not-listed","checkedAt":"2026-10-28T23:45:31.121Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
