How to Fix CVE-2025-27097

To remediate this vulnerability, upgrade all affected @graphql mesh/runtime dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@graphql-mesh/runtime fixed: 0.96.9 
npm install @graphql-mesh/runtime@0.96.9
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls @graphql-mesh/runtime

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2025-27097, inspect your project dependencies using npm:

npm ls @graphql-mesh/runtime

Analyze the terminal output to locate any version of @graphql mesh/runtime in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.96.9), your application is affected.

Note: The npm ls @graphql-mesh/runtime command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In @graphql mesh/runtime, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

When you have transforms on the root level or single source with transforms, and the client sends the same query with different variables, the initial variables are used in all following requests until the cache evicts DocumentNode. Let's say if a token is sent via variables, the following requests will act like the same token is sent even if the following requests have different tokens. This can cause a short memory leak but it won't grow per each request but per different operation until the cache evicts DocumentNode by LRU mechanism.
