EchelonGraph scoreLOW confidence

This critical-severity CVE scores 9.3 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit probability: 0.0%, top 93% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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/sqlite@2.2.2, @cap-js/postgres@2.2.2, and @cap-js/db-service@2.10.1 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.
