CVE-2022-1911Network attack vector

Unauthenticated installed-application disclosure via parser error

Published Nov 30, 2022 · Updated Feb 23, 2026

Information disclosure in M-Files Server before 22.6.11534.1 and before 22.6.11505.0 allows remote attackers to query installed applications. An unspecified parser function exposes operating-system information about some installed applications when it processes an unauthenticated query. M-Files has not published the affected function or request field; no user interaction is required, and file and document data are not exposed.
