Last modified Jun 25, 2026

CVE-2026-12755 is a low-severity vulnerability rated 2.7/10 on the CVSS scale. 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.. EPSS estimates a 0.22% chance of exploitation in the next 30 days.
