Executive Summary

This vulnerability involves sensitive information being inserted into data sent through the automation jobs API in Devolutions PowerShell Universal versions 2026.2.2 and earlier. An authenticated user with specific read permissions can access another user's stored OAuth refresh token via job read responses that fail to remove this sensitive data.

Impact Analysis

If exploited, this vulnerability could allow an attacker with limited access to obtain another user's OAuth refresh token. This token could then be used to gain unauthorized access to the victim's resources or data, potentially leading to further compromise of sensitive information or systems.

Compliance Impact

This vulnerability could potentially impact compliance with GDPR and HIPAA by exposing OAuth refresh tokens through job read responses. Unauthorized access to such tokens may lead to unauthorized data access or processing, violating confidentiality and integrity requirements under these regulations.

Mitigation Strategies

Upgrade Devolutions PowerShell Universal to a version later than 2026.2.2 to address the vulnerability.
