CVE-2024-9333Network attack vector

Document disclosure via incorrect ACL calculation

Published Oct 2, 2024 · Updated Feb 23, 2026

Improper permission preservation in M-Files Connector for Copilot before 24.9.3 allows remote authenticated users to read limited documents. The connector calculates an object's ACL incorrectly before sending it to Microsoft Graph, so the published ACL can differ from the M-Files ACL. Exploitation requires an authenticated account and metadata-based permissions; exposure is limited to documents the account should not read.
