Description
The SAP Cloud Application Programming Model is a tool for building enterprise-grade cloud applications, and cap-js/cds-dbs is the monorepo for SQL database services for that tool. On April 29, 2026, compromised versions of `@cap-js/[email protected]`, `@cap-js/[email protected]`, and `@cap-js/[email protected]` were 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. User should upgrade to `@cap-js/sqlite` >= 2.4.0, `@cap-js/postgres` >= 2.3.0, `@cap-js/db-service` >= 2.11.0. If a compromised version was ever installed, rotate all affected credentials. No known workarounds are available.
