CVE-2026-90969: CWE-284 Improper access control in Devolutions Server
CVE-2026-90969 is an improper access control vulnerability in Devolutions Server versions up to 2026.2.16. It allows an authenticated user without the view-password permission to retrieve cleartext passwords by exploiting the vault entry listing feature with specific request parameters.
AI Analysis
Technical Summary
This vulnerability involves improper access control in the vault entry listing feature of Devolutions Server 2026.2.16 and earlier. An authenticated user lacking the required view-password permission can send a specially crafted request to the entry listing endpoint with password disclosure parameters, resulting in unauthorized disclosure of cleartext passwords.
Potential Impact
An attacker with valid authentication but without explicit permission to view passwords can obtain sensitive cleartext passwords from the vault. This compromises the confidentiality of stored credentials, potentially leading to further unauthorized access or privilege escalation within the environment.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the vault entry listing feature to trusted users only and monitor for unusual access patterns related to password retrieval attempts.
