Executive Summary

This vulnerability is a missing authorization issue in Devolutions Server versions 2026.3.5.0 and earlier. An authenticated non-administrative user can exploit a crafted API request to disclose integration secrets from the data source settings API.

Detection Guidance

To detect this vulnerability, check Devolutions Server logs for unauthorized API requests to the integration settings endpoint. Look for non-administrative users accessing sensitive data source settings. Ensure all authenticated users have appropriate permissions and review API access logs for suspicious activity.

Impact Analysis

An attacker with access could steal sensitive integration secrets, potentially leading to unauthorized access to connected systems or data breaches. This could compromise the confidentiality and integrity of stored information.

Compliance Impact

This vulnerability could lead to unauthorized data exposure, violating GDPR's data protection principles or HIPAA's security requirements for protected health information. Compliance may be compromised if integration secrets grant access to regulated data.

Mitigation Strategies

Immediately upgrade Devolutions Server to version 2026.2.18.0, 2026.3.7.0, or higher to patch the missing authorization flaw. Temporarily restrict non-administrative user access to integration settings until the upgrade is complete.
