CVE-2025-26683
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 · uneditedImproper authorization in Azure Playwright allows an unauthorized attacker to elevate privileges over a network.
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 confidenceAzure Playwright contains an improper authorization vulnerability that allows an unauthenticated attacker to elevate privileges via network access. The vulnerability stems from insufficient authorization checks that can be exploited to gain higher-level access than intended.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 Azure Playwright deploymentSearch your Azure subscription for any resources or services named 'Playwright' or related to Azure Playwright testing infrastructure using Azure CLI: az resource list --query "[?contains(name, 'playwright')]" or via Azure Portal resource searchAffected if Azure Playwright resources or services are found in the subscription
-
Check for Playwright testing resourcesReview Azure Resource Manager templates, Terraform configurations, or infrastructure-as-code repositories for Playwright-related resources, and check Azure Portal for any Playwright test execution services or containersAffected if Playwright-based testing infrastructure exists in the environment
-
Review RBAC role assignmentsExecute: az role assignment list --assignee <service-principal-or-user-running-playwright> --output table to list all role assignments for accounts used by Playwright servicesAffected if Accounts running Playwright have overly permissive roles (Contributor, Owner, or high-privilege custom roles)
-
Audit Playwright service endpoint exposureCheck Azure network configuration for any public endpoints exposed for Playwright test services: az network vnet list and review NSG rules for test runner portsAffected if Playwright services have public-facing network endpoints without authentication requirements
-
Inspect API permissions for Playwright identitiesRun: az ad app permission list --id <application-id-of-playwright-app> to review Microsoft Graph and Azure API permissions granted to Playwright service principalsAffected if Playwright service principals have excessive API permissions beyond what testing requires
If Azure Playwright is deployed in your environment with high-privilege RBAC roles or public network exposure, you are likely affected by this authorization bypass vulnerability.

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 dataApply vendor patches from Microsoft for Azure Playwright when available. Until patched, restrict network access to Playwright instances and implement additional authentication layers where possible.
