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.","published_at":"2026-06-25T22:43:47.441000Z","last_modified_at":null,"cvss_v3_score":6.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-22"],"nvd_references":["https://github.com/Cacti/cacti/security/advisories/GHSA-mjvw-mhj5-9jcj","https://github.com/Cacti/cacti/commit/4c09efaebf3a9faec66969d0b5c4aceaf397f37f"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-28T17:53:49.239492Z","updated_at":"2026-06-28T23:30:10.460975Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"cacti","vendor_name":"Cacti","product_slug":"cacti","product_name":"cacti","version_start":"< 1.2.31","version_start_inclusive":true,"version_end":"< 1.2.31","version_end_inclusive":true,"cpe23_uri":"cve5:cacti:cacti:< 1.2.31:< 1.2.31"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/Cacti/cacti/security/advisories/GHSA-mjvw-mhj5-9jcj","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/Cacti/cacti/commit/4c09efaebf3a9faec66969d0b5c4aceaf397f37f","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-06-25T22:43:47.441000Z","label":"CVE published","source":null}]}
