CVE-2023-6335

Filename control via improper link resolution

Published Jan 16, 2024 · Updated Jun 2, 2025

Link following in HYPR Workforce Access before 8.7 on Windows allows local users to control a filename during file access. The published record does not identify the file-access locus or explain which link type is resolved to an unintended target. Exploitation requires low-privileged local access and a high-complexity condition; the disclosed consequence stops at attacker control of the filename.
