CVE-2026-13437: CWE-201 Insertion of Sensitive Information Into Sent Data in Devolutions PowerShell Universal
Insertion of sensitive information into sent data in the AI Agent job API in Devolutions PowerShell Universal 2026.2.0 allows an authenticated user with AI Agent read access to obtain reusable, potentially higher-privileged authentication tokens via App Tokens serialized in plaintext in job API responses.
AI Analysis
Technical Summary
This vulnerability involves the insertion of sensitive information, specifically App Tokens, into the data sent by the AI Agent job API in Devolutions PowerShell Universal version 2026.2.0. Authenticated users with AI Agent read access can access these tokens as they are serialized in plaintext in the API responses. The tokens are reusable and potentially grant higher privileges, posing a risk of privilege escalation or unauthorized access within the affected system.
Potential Impact
An authenticated user with AI Agent read access can retrieve plaintext serialized App Tokens from the job API responses. These tokens are reusable and may grant higher privileges than the user's original access level, increasing the risk of unauthorized actions or privilege escalation within the PowerShell Universal environment.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround has been documented at this time. Until a patch is available, restrict AI Agent read access to trusted users only and monitor for unusual token usage patterns.
