{"id":"DEBIAN-CVE-2026-40084","details":"Cacti is an open source performance and fault management framework. 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.","modified":"2026-09-14T17:03:10.417853752Z","published":"2026-06-25T23:17:03.030Z","upstream":["CVE-2026-40084"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-40084"}],"affected":[{"package":{"name":"cacti","ecosystem":"Debian:12","purl":"pkg:deb/debian/cacti?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.24+ds1-1","1.2.24+ds1-1+deb12u1","1.2.24+ds1-1+deb12u2","1.2.24+ds1-1+deb12u3","1.2.24+ds1-1+deb12u4","1.2.24+ds1-1+deb12u5","1.2.25+ds1-1","1.2.25+ds1-2","1.2.26+ds1-1","1.2.27+ds1-1","1.2.27+ds1-2","1.2.28+ds1-1","1.2.28+ds1-2","1.2.28+ds1-3","1.2.28+ds1-4","1.2.30+ds1-1","1.2.30+ds1-2","1.2.30+ds1-3","1.2.31+ds1-1","1.2.31+ds1-2","1.2.31+ds1-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-40084.json"}},{"package":{"name":"cacti","ecosystem":"Debian:13","purl":"pkg:deb/debian/cacti?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.30+ds1-1","1.2.30+ds1-2","1.2.30+ds1-3","1.2.31+ds1-1","1.2.31+ds1-2","1.2.31+ds1-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-40084.json"}},{"package":{"name":"cacti","ecosystem":"Debian:14","purl":"pkg:deb/debian/cacti?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.2.31+ds1-1"}]}],"versions":["1.2.30+ds1-1","1.2.30+ds1-2","1.2.30+ds1-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-40084.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
