No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Improper input validation in the PAM AD discovery endpoints in Devolutions Server 2026.2.4.0 through 2026.2.7.0 allows an authenticated user with the UserGroupsView permission to coerce server-side authentication to an attacker-controlled host, exposing PAM provider credentials as a NTLMv2 challenge-response, via a crafted DomainName parameter.
