Answer in brief
CVE-2026-40084 records a Medium severity (CVSS 6.5) path traversal vulnerability in CVE-2026-40084. The source record does not mark it as known exploited. No package mapping is present, so exposure must be confirmed against the affected product and deployment inventory.
Answer in brief
CVE-2026-40084 records a Medium severity (CVSS 6.5) path traversal vulnerability in CVE-2026-40084. The source record does not mark it as known exploited. No package mapping is present, so exposure must be confirmed against the affected product and deployment inventory.
Review the upstream advisory, identify the affected product in your inventory, and apply the vendor update when one is available.
Path Traversal describes the vulnerability class recorded for this advisory. The current record does not mark CVE-2026-40084 as known exploited; continue to monitor the source for status changes. This is a product-level record in the current feed, not a package-level dependency mapping.
Affected software not mapped. Review the upstream record for vendor-specific product and version guidance.
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.
