{"identifier":"CVE-2026-58256","cve":{"id":"CVE-2026-58256","description":"GRR is a resource management and reservation application. Prior to the advisory-reported fixed version 4.5.0, an administrator can inject malicious PHP through LDAP connector configuration parameters such as `ldap_filter`, poisoning `/personnalisation/config_ldap.inc.php` and permitting remote code execution. The administrator must first successfully connect to an LDAP server, which can be attacker-controlled, and then submit malicious input on the subsequent connector settings page. The advisory reports this issue as fixed in version 4.5.0.","published":"2026-10-27T23:17:06.140000+00:00","modified":"2026-10-28T14:21:52.187000+00:00","status":"Deferred","score":9.1,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","cvss_version":"3.1","affected":[],"weaknesses":["CWE-94"],"references":[{"url":"https://github.com/JeromeDevome/GRR/commit/3ff9504ae557da1e8e208149acbf8c7f04de645f","source":"security-advisories@github.com"},{"url":"https://github.com/JeromeDevome/GRR/security/advisories/GHSA-fp4f-xmw6-5jf8","source":"security-advisories@github.com"},{"url":"https://github.com/JeromeDevome/GRR/tree/v4.5.0","source":"security-advisories@github.com"}],"kev":null,"kev_checked":true,"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","baseScore":9.1,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"HIGH","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.3,"impactScore":6.0}]},"configurations":[],"source":"nvd","retrieved_at":"2026-10-28T16:45:35.245889+00:00","exploited":false,"kev_stale":false,"products":[],"priority":{"label":"Critical technical severity","reasons":["CVSS is at least 9.0; exploitation is not established by severity alone."]},"epss":{"probability":0.00575,"percentile":0.47362,"date":"2026-10-29","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"github.com","source_url":"https://github.com/JeromeDevome/GRR/commit/3ff9504ae557da1e8e208149acbf8c7f04de645f","investigate_url":"https://investigate.aeglixmind.com/#github.com"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-58256","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-58256","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-58256","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
