CVE-2026-15058Network attack vector

Message deletion via user-controlled object reference

Published Jul 14, 2026 · Updated Jul 14, 2026

Improper authorization in Devolutions Server 2026.2.11 and 2026.1.22 allows remote authenticated users to delete other users’ messages. The secure messages deletion endpoint accepts a message identifier and deletes the referenced message without verifying that it belongs to the caller. Any authenticated account can target another user’s identifier, causing unauthorized message deletion without exposing or modifying other server data.
