Improper authorization in the Active Directory browsing feature in Devolutions Server allows a low-privileged authenticated user to obtain authentication material associated with a stored PAM provider service account via authentication relay to an attacker-controlled server.
This issue affects :
- Devolutions Server 2026.1.6.0 through 2026.1.16.0
- Devolutions Server 2025.3.20.0 and earlier
AnalysisAI
Credential disclosure in Devolutions Server (2026.1.6.0-2026.1.16.0 and 2025.3.20.0 and earlier) lets a low-privileged authenticated user coerce the server's Active Directory browsing feature into authenticating against an attacker-controlled host, relaying the stored PAM provider service-account credentials. Classified as SSRF (CWE-918), it enables theft of privileged service-account authentication material that can then be abused against downstream systems. No public exploit identified at time of analysis; EPSS is very low (0.04%, 11th percentile) and CISA SSVC rates exploitation as none.
Technical ContextAI
Devolutions Server is a self-hosted privileged access management (PAM) and credential/remote-connection platform used to broker and vault privileged accounts. The flaw sits in the Active Directory browsing feature, which performs outbound authentication to a directory endpoint on the user's behalf. Because the target endpoint is not properly authorized/validated, a user can point it at an attacker-controlled server and capture the relayed authentication handshake - a classic Server-Side Request Forgery (CWE-918) pattern where the trusted server is tricked into initiating a request/authentication to an attacker-chosen destination. The material exposed is the stored PAM provider service account's credentials, which are typically high-value because that account is used to manage other privileged accounts. The CPE cpe:2.3:a:devolutions:server covers all affected builds.
RemediationAI
Patch available per vendor advisory (DEVO-2026-0013, https://devolutions.net/security/advisories/DEVO-2026-0013/): upgrade to a fixed build above the affected ranges - a release later than 2026.1.16.0 on the 2026.1 branch, or later than 2025.3.20.0 on the 2025.3 branch (confirm the exact patched version directly in the advisory, as the input does not state a specific fix build). As compensating controls until patched, restrict or disable use of the Active Directory browsing feature for low-privileged roles, and tighten which accounts may configure or trigger AD browsing; apply egress network filtering so the Devolutions Server cannot initiate outbound authentication to arbitrary/attacker-controlled hosts (restrict directory traffic to known internal domain controllers) - note this may break legitimate AD lookups to unlisted domains. Additionally, rotate the PAM provider service-account credentials after patching in case they were already exposed, and monitor for unexpected outbound authentication attempts from the server.
