CVE-2026-13437
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedInsertion 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe AI Agent job API in Devolutions PowerShell Universal 2026.2.0 exposes App Tokens in plaintext within job API responses. Authenticated users with AI Agent read access can obtain these reusable, potentially higher-privileged authentication tokens, enabling privilege escalation or unauthorized access.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify PowerShell Universal versionRun 'Get-UAServer -ComputerName localhost' or check the installation directory for version information (typically in Program Files\Devolutions\PowerShell Universal\version.json or similar)Affected if Version is exactly 2026.2.0.0
-
Confirm AI Agent module is installedRun 'Get-UAInstalledModule' or check the modules folder under the PowerShell Universal installation for the AI Agent moduleAffected if AI Agent module is present and loaded in the environment
-
Check for exposed App Tokens in job outputInvoke the AI Agent job API endpoint (typically /api/agent/jobs or similar) using Invoke-RestMethod with valid authentication and inspect responses for plaintext 'appToken' or 'token' fields in job metadataAffected if Job API responses contain plaintext authentication tokens in any field
-
Review API audit logs for token exposureExamine PowerShell Universal logs in the 'Logs' folder or query the audit API endpoint for job execution records that may contain serialized credentialsAffected if Logs show job responses include token or credential data in the output fields
You are affected if running PowerShell Universal version 2026.2.0.0 with AI Agent enabled and the job API returns plaintext authentication tokens in responses.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataRemove App Token serialization from job API responses; implement filtering to exclude sensitive credential data from API output; validate that API endpoints only return necessary job metadata and not authentication artifacts.
