CVE-2026-9248Network attack vector

Authenticated vault-file disclosure via entry duplication

Published May 22, 2026 · Updated May 22, 2026

Authorization bypass in affected Devolutions Server versions allows remote authenticated users to copy inaccessible vault files via crafted requests. The entry duplication save path trusts a caller-supplied source-entry identifier without checking read access; affected releases are 2025.3.20.0 and earlier and 2026.1.6.0 through 2026.1.16.0. Reachability requires write access to any vault and active user interaction; disclosure is limited to source-entry documentation and attachments.
