CVE-2025-43018Network attack vector

Unauthenticated address-book information disclosure

Published Jul 30, 2025 · Updated Jul 30, 2025

Information disclosure in HP LaserJet Pro printer firmware allows remote attackers to read local address-book entries without authentication. The printer's address-book query path returns stored entries without requiring administrator credentials; HP has not disclosed the responsible endpoint or implementation error. Network access to the printer is sufficient, and the documented consequence is limited to exposure of address-book data.
