CVE-2026-12553Network attack vector

Arbitrary file access via DLL hijacking

Published Aug 17, 2026 · Updated Aug 17, 2026

DLL hijacking in HP Web Jetadmin before 10.6 allows remote attackers to read or write arbitrary files via network requests. HP and the CNA record do not disclose the specific module or DLL load path, only that a DLL hijacking condition is the mechanism behind the arbitrary file access. The published CVSS record treats the issue as reachable without authentication or user interaction; public sources do not describe code execution beyond read and write access on the Web Jetadmin host.
