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."}], "lastModified": "2026-06-29T18:48:17.770", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:cacti:cacti:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "5406B2E1-D53C-45AC-8F93-CFCAEDC1B5F8", "versionEndExcluding": "1.2.31"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
