# GHSA-jpvj-wpmj-h7rv: Supply chain compromise via malicious @cap-js/openapi

## Affected packages

- npm `@cap-js/openapi` = 1.4.1 → fixed: 1.4.2

## Details

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 - Developer FAQ
