CVE-2026-58467 — Cockpit CMS security vulnerability

High CVSS 8.2

Cockpit CMS through 2.14.0 contains a path traversal and local file inclusion vulnerability that allows unauthenticated attackers to read arbitrary files or execute PHP files by including unvalidated PATH_INFO derived from REQUEST_URI in filesystem path construction without containment checks. Attackers can inject dot-dot sequences into the URL to traverse outside the designated spaces directory, and when the resolved path ends with a .php extension, the application passes it to include(), enabling local file inclusion on deployments using the PHP built-in server or certain non-default Nginx configurations.

Matched remediation archetype

Path traversal, unsafe upload, and file handling

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
  • Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
  • Review canonicalization and containment checks across supported operating systems and storage backends.

Remediate safely

  • Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
  • Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
  • Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
