{"id":"CVE-2026-40079","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-40079","generatedAt":"2026-10-28T03:29:27.196Z","title":"Versions 1.2.30 and prior are vulnerable to Command Injection due to lack of sanitization in the escape_command() function.","description":"Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior are vulnerable to Command Injection due to lack of sanitization in the escape_command() function. The escape_command() function at lib/rrd.php is a no-op: it returns $command unchanged. The command line built by rrdtool_function_graph() is passed through this function and then to shell_exec($full_commandline). The risk is in __rrd_execute() where text_format values from graph templates (which may contain host variable substitutions) reach shell_exec without adequate escaping. This issue has been addressed in version 1.2.31.","published":"2026-06-25T00:17:48.000Z","lastModified":"2026-06-26T00:16:52.000Z","status":"Analyzed","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"4.0","score":8.6,"severity":"HIGH","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:L/SI:L/SA:L/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-78","CWE-88"],"affected":["cacti/cacti"],"epss":{"score":0.0169,"percentile":0.76901,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (1.69%).
