CVE-2026-15641Network attack vector

Access approval bypass via unchecked self-approval

Published Jul 14, 2026 · Updated Jul 14, 2026

Improper authorization in Devolutions Server before 2026.1.23 or 2026.2.12 allows remote authenticated users to self-approve access requests. The access request status endpoint accepts a requester's direct approval call without enforcing the separate approver review. A low-privileged account and a pending access request are required; exploitation changes the request to approved without the required review.
