CVE-2026-86055

Part-DB is an open source inventory management system for electronic components. 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.
