{"cve":"CVE-2026-40079","nvd":{"published":"2026-06-25T00:17:47.570","modified":"2026-06-26T00:16:51.910","status":"Analyzed","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.","cvss_v4":{"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","score":8.6},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-78","CWE-88"],"references":["https://github.com/Cacti/cacti/commit/4c09efaebf3a9faec66969d0b5c4aceaf397f37f","https://github.com/Cacti/cacti/security/advisories/GHSA-xq98-376r-hv9j"],"products":["cacti:cacti"],"source":"nvd","synced_at":"2026-10-19T22:41:17.107060303+00:00"},"epss":{"cve":"CVE-2026-40079","score":0.0169,"percentile":0.77064,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
