{"schema":"threatline.record/2","record":{"id":"CVE-2026-58205","aliases":["GHSA-r6x2-w38j-vvq2"],"summary":"GRR has a Reflected XSS issue","details":"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.","categories":["Unclassified"],"product":"GRR","vendor":"JeromeDevome","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-58205","source_modified_at":"2026-10-27T22:26:14.705Z","fetched_at":"2026-10-28T01:10:53.534015Z","product":"GRR","vendor":"JeromeDevome","versions":[{"status":"affected","version":"< 4.5.0"}],"defaultStatus":null}],"fixed_versions":[],"cvss":8.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00287,"percentile":0.21229,"score_date":"2026-10-28"},"published_at":"2026-10-27T22:26:14.705Z","modified_at":"2026-10-27T22:26:14.705Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-58205","fetched_at":"2026-10-28T01:10:53.534015Z","source_modified_at":"2026-10-27T22:26:14.705Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-58205","fetched_at":"2026-10-28T15:55:58.673066Z","source_modified_at":"2026-10-28"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/JeromeDevome/GRR/security/advisories/GHSA-r6x2-w38j-vvq2","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/JeromeDevome/GRR/commit/4ef77f91818215c1f8e0f06023d89257dfd61c68","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/JeromeDevome/GRR/tree/v4.5.0","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-27T22:26:14.705Z","content_hash":"33bdbae56c116a7ef0aabef17d0605fde41d1f2767bd70441ed4f89666487978"}}
