Summary
by MITRE • 07/29/2026
Improper certificate validation in the Devolutions Server connection handling in Devolutions Password Manager 2026.2.1.0 and earlier on Android, iOS, and macOS allows an adjacent-network attacker to intercept and modify sensitive information via a forged TLS certificate.

This vulnerability represents a critical flaw in the cryptographic security implementation of Devolutions Password Manager across multiple mobile and desktop platforms. The issue stems from inadequate certificate validation mechanisms within the application's connection handling process, specifically affecting versions prior to 2026.2.1.0 on Android, iOS, and macOS operating systems. The weakness allows attackers positioned within the same network segment to perform man-in-the-middle attacks by presenting forged TLS certificates that the application fails to properly validate. This failure in certificate validation creates a significant security gap that directly violates fundamental principles of secure communications and data protection.
The technical flaw manifests as a failure to implement proper certificate chain validation, hostname verification, or trust anchor checking during TLS handshake procedures. Attackers can exploit this by intercepting network traffic between the password manager application and its backend services, presenting malicious certificates that appear legitimate to the vulnerable client. This allows them to decrypt, modify, or redirect sensitive authentication data, passwords, and other confidential information flowing through the application's secure channels. The vulnerability operates at the transport layer security level and specifically relates to improper implementation of X.509 certificate validation procedures that should be enforced according to industry standards.
The operational impact of this vulnerability extends beyond simple data interception to encompass complete compromise of user authentication credentials and sensitive password information stored within the password manager. An adjacent-network attacker can manipulate all communication channels between the client application and server infrastructure, potentially gaining access to multiple user accounts, service credentials, and confidential enterprise data. This represents a severe confidentiality breach that undermines the core security promise of password management solutions, particularly affecting users who rely on these applications for storing critical authentication information.
Organizations and individual users should immediately update to Devolutions Password Manager version 2026.2.1.0 or later to remediate this vulnerability. System administrators should also consider implementing additional network-level protections such as DNS security extensions and monitoring for suspicious certificate behavior. The vulnerability aligns with CWE-295 which addresses improper certificate validation, and corresponds to ATT&CK technique T1566 which covers phishing through spearphishing campaigns that can leverage such certificate validation flaws. Network segmentation and endpoint detection and response solutions should be deployed as additional mitigations while waiting for the official patch deployment.
