CVE-2026-42213Public exploitNetwork attack vector

File probing and NTLM leak via unchecked paths

Published May 8, 2026 · Updated May 8, 2026

Path traversal in anzory Postprocessor IDE for SolidCAM 1.0.0 through 1.0.1 allows attackers to probe files and leak NTLM hashes via GPPL files. GpplDocumentLinkHandler accepts absolute, parent-relative, subfolder, and UNC inc paths and calls File.Exists while creating document links. Opening a hostile .gpp file triggers checks before any link click, revealing file-existence results and sending Windows SMB authentication to an attacker-controlled host.
