CVE-2025-4493Network attack vector

Unauthorized group privileges via JIT set misassignment

Published May 28, 2025 · Updated May 28, 2025

Improper privilege assignment in Devolutions Server allows remote authenticated users to issue PAM JIT requests for unauthorized groups. The JIT privilege-set interface assigns every available provider group instead of preserving the set's intended group restrictions. Exposure requires enabled, configured PAM JIT privilege sets in 2025.1.3.0 through 2025.1.7.0 or 2024.3.15.0 and earlier.
