Supply chain compromise via malicious @cap-js/openapi

Impact

On May 19, 2026, a compromised version of @cap-js/[email protected] 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.
