Prior to version 2.13.3, Part-DB builds the absolute URL of the password-reset link it emails to a user from the client-supplied HTTP Host header, with no trusted-host validation. An unauthenticated attacker who submits a forgot-password request for a known account while sending a spoofed Host header causes Part-DB to email that account a reset link whose hostname is attacker-controlled, while still embedding the genuine reset token. When the victim opens the link (or an automated inbound mail-security scanner dereferences it), the valid token is disclosed to the attacker, who replays it against the real instance to set a new password and take over the account. Because the seeded admin account can be targeted, this yields full pre-authentication administrative account takeover. This issue has been patched in version 2.13.3.","state":0,"publishedAt":"2026-10-23T04:09:27.051+00:00","modifiedAt":"2026-10-23T04:09:27.051+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\": \"< 2.13.3\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"}],"references":["https://github.com/Part-DB/Part-DB-server/security/advisories/GHSA-m9rf-69wp-c56r","https://github.com/Part-DB/Part-DB-server/releases/tag/v2.13.3"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-86055","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-86055","identifiers":["CVE-2026-86055"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
