Unrestricted file upload in Cockpit CMS versions up to and including 2.6.0 allows any authenticated user to upload PHP scripts via the asset upload endpoint, achieving remote code execution as the web server process. The root cause is the default wildcard (*) value for the allowed_uploads configuration combined with storage of uploaded files in a web-accessible directory - a textbook CWE-434 condition. No public exploit has been identified at time of analysis and the vulnerability is not listed in CISA KEV, but the low barrier of entry (any authenticated account) makes this a high-priority remediation target for internet-facing deployments.
Path-traversal privilege escalation in Cockpit CMS Bucket file storage API (before 2.14.0) lets an authenticated low-privileged user bypass per-bucket isolation by supplying a '../' bucket name, granting cross-bucket read, upload, and delete over all files regardless of owner or role. The flaw stems from an incomplete sanitization regex that strips dangerous characters but preserves dot sequences, which Flysystem then normalizes down to the storage root. No public exploit is identified at time of analysis, though a proof-of-concept gist is referenced; the issue was reported by VulnCheck and a vendor patch is available.
Broken access control in Cockpit CMS's Bucket file storage API (/system/buckets/api) lets any authenticated user, regardless of assigned role, execute all bucket file operations (list, upload, delete, rename, create folder) against any named bucket - including admin-only buckets. VulnCheck reported the flaw and publicly available exploit code exists (proof-of-concept gist), but there is no evidence of active exploitation. With a CVSS 4.0 score of 8.7 and full confidentiality/integrity/availability impact on stored files, it enables privilege escalation of file-storage capabilities across tenant boundaries within the CMS.
Unauthenticated remote file and directory exposure in agentejo Cockpit CMS 0.12.2 and earlier allows attackers to access files outside the web root via path traversal through the htaccess Handler's YAML configuration loader. The root cause is CWE-552 (Files or Directories Accessible to External Parties), triggered by unsafe processing of /config/config.yaml via the Spyc::YAMLLoad function, which can expose sensitive configuration data including credentials or internal path structures. A public exploit proof-of-concept exists on GitHub; no vendor patch has been issued, as the vendor did not respond to coordinated disclosure.
Authenticated remote code execution in Cockpit CMS lets attackers holding collection-management privileges inject arbitrary PHP through the /cockpit/collections/save_collection endpoint's rule parameters, which are persisted to server-side PHP files and executed via include(). A low-privileged authenticated user can therefore run arbitrary OS commands on the host. Publicly available exploit code exists (VulnCheck advisory and a public gist), though this is not listed in CISA KEV; EPSS is modest at 0.39% (60th percentile).
