CVE-2025-14267Network attack vector

Information disclosure via retained activity-feed cache

Published Dec 19, 2025 · Updated Dec 19, 2025

Information disclosure in M-Files Server before 25.12.15491.7 allows remote authenticated users to expose source-vault activity data. The metadata-structure-only vault copy path fails to remove temporary activity-feed cache records, allowing them to enter the target vault. An administrator must create the copy after source-vault activity exists; matching object versions and internal IDs can expose file names, user names, and comments.
