How to Fix GHSA-jpvj-wpmj-h7rv

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

@cap-js/openapi fixed: 1.4.2 
npm install @cap-js/openapi@1.4.2
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 @cap-js/openapi

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-jpvj-wpmj-h7rv, inspect your project dependencies using npm:

npm ls @cap-js/openapi

Analyze the terminal output to locate any version of @cap js/openapi in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.4.2), your application is affected.

Note: The npm ls @cap-js/openapi 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-506: Embedded Malicious Code, where the product contains code that appears to be malicious in nature. In @cap js/openapi, 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

### Impact On May 19, 2026, a compromised version of @cap-js/openapi@1.4.1 was published. The malicious packages harvested credentials and attempted self-propagation. If a compromised version was installed, all credentials accessible on that machine (npm tokens, cloud provider credentials, SSH keys, GitHub PATs) should be considered compromised. ### Patches Upgrade to @cap-js/openapi >= 1.4.2 If the compromised version was ever installed, rotate all affected credentials. ### Workarounds No workarounds. ### References - [SAP Note 3747787](https://me.sap.com/notes/3747787) - [Developer FAQ](https://www.sap.com/documents/2026/05/8203a8b9-4d7f-0010-bca6-c68f7e60039b.html)
