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." } ], "source": { "advisory": "GHSA-m9rf-69wp-c56r", "discovery": "UNKNOWN" } }, "adp": [ { "references": [ { "url": "https://github.com/Part-DB/Part-DB-server/security/advisories/GHSA-m9rf-69wp-c56r", "tags": [ "exploit" ] } ], "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-10-29T12:52:45.808126Z", "id": "CVE-2026-86055", "options": [ { "Exploitation": "poc" }, { "Automatable": "yes" }, { "Technical Impact": "total" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-10-29T12:56:48.256Z" } } ] } }
