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.","epss":{"date":"2026-11-02","percentile":0.47431,"score":0.00575},"exploits":[],"kev":null,"metrics":[{"score":9.1,"severity":"critical","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1793708193287,"publishedAt":1793140332589,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/JeromeDevome/GRR/security/advisories/GHSA-fp4f-xmw6-5jf8"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/JeromeDevome/GRR/commit/3ff9504ae557da1e8e208149acbf8c7f04de645f"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/JeromeDevome/GRR/tree/v4.5.0"}],"remediation":[],"revision":"df1c82a0165dd19eed4b0cf5787381a0be19d94c411885fa5e70e06b770f0540","sources":[{"modifiedAt":1793708193287,"name":"CNA: GitHub_M","retrievedAt":1793711389562,"url":"https://www.cve.org/CVERecord?id=CVE-2026-58256"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793711399249,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-58256"}],"ssvc":{"assessedAt":1793708171914,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"total"},"status":"published","title":"GRR vulnerable to Remote Code Execution Via PHP Code Injection","updatedAt":1793711399249}
