Versions 1.2.30 and prior are vulnerable to Path Traversal  through the Report format_file Parameter, causing arbitrary file read. This vulnerability occurs in two stages. In the first stage (stored injection), lib/html_reports.php at line 283 stores $save['format_file'] =  $post['format_file'] directly into the database without any validation. In the second stage (file read), lib/reports.php at line 667 concatenates  CACTI_PATH_FORMATS . '/' . $format_file, and line 670 then calls file($format_file), reading arbitrary files from the filesystem. This issue has been fixed in version 1.2.31."}],"source":{"advisory":"GHSA-mjvw-mhj5-9jcj","discovery":"UNKNOWN"}},"adp":[{"references":[{"url":"https://github.com/Cacti/cacti/security/advisories/GHSA-mjvw-mhj5-9jcj","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-06-26T12:44:34.528149Z","id":"CVE-2026-40084","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-06-26T12:44:37.984Z"}}]}}
