CVE-2026-25827Network attack vector

Admin-only file enumeration via unrestricted path properties

Published Sep 15, 2026 · Updated Sep 15, 2026

File enumeration in Keyfactor SignServer before 7.6.0 allows remote authenticated users to confirm server-side file paths. The ATTRIBUTESFILE, KEYSTOREPATH, and TRUSTSTOREPATH properties accept unrestricted administrator-supplied paths and expose file existence through format or missing-file errors returned to the client. Administrative access is required, and the oracle confirms whether application-server-readable paths exist without disclosing file contents.
