Prior to version 2.12.1, the part attachment upload handler stores uploaded files under the web-served media directory using the client-supplied file extension, and its extension blocklist does not include phar. AttachmentSubmitHandler::renameBlacklistedExtensions() rewrites dangerous extensions (php, phtml, sh, cgi, py, js, html, htaccess, ...) to .txt, but phar is absent from the list, so a .phar file keeps its extension. Public attachments (the default) are written into public/media/, which is the Apache document root. The shipped Apache configuration routes .phar to PHP-FPM, so the stored file is executed as PHP on request. The per-attachment-type extension filter is empty by default and is not consulted by the upload handler in a way that blocks this, and a non-admin user in the default users group can create an attachment type with no filter and attach files to parts. Any authenticated user in the default users group uploads a .phar attachment to a part and fetches it under /media/, executing arbitrary PHP as the www-data web user. Ability to exploit depends on the webserver config, docker image contained the vulnerability by default. This issue has been patched in version 2.12.1.","state":0,"publishedAt":"2026-10-23T03:48:59.951+00:00","modifiedAt":"2026-10-23T03:48:59.951+00:00","affected":[{"ecosystem":"Vendor product","name":"Part-DB-server","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Part-DB\",\n                    \"product\": \"Part-DB-server\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.12.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N","score":9.6,"severity":"CRITICAL"}],"references":["https://github.com/Part-DB/Part-DB-server/security/advisories/GHSA-w5m7-3xf7-6g7g","https://github.com/Part-DB/Part-DB-server/releases/tag/v2.12.1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-54630","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-54630","identifiers":["CVE-2026-54630"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
