Which versions of PostgreSQL are affected by CVE-2026-46421?

Three SAP CAP Node.js database packages (@cap-js/sqlite@2.2.2, @cap-js/postgres@2.2.2, @cap-js/db-service@2.10.1) were compromised at the source on April 29, 2026, delivering credential-harvesting…. A patch is available.

How to fix or mitigate CVE-2026-46421?

Within 24 hours: Identify all machines and CI systems that installed the three affected package versions using npm audit logs, dependency manifests, and CI history; immediately rotate all credentials (npm tokens, cloud API keys, SSH keys, GitHub personal access tokens, database passwords) for any developer or service account that may have used these packages. Within 7 days: Scan all affected systems for unauthorized access, lateral movement attempts, and command-and-control beacons; apply vendor-released patch to upgrade beyond the compromised versions; conduct forensic review of git commits, deployments, and infrastructure changes made from affected systems during the exposure window. Within 30 days: Conduct full supply-chain audit of npm dependencies with focus on all transitive dependencies; implement cryptographic signature verification for all npm installations; require MFA on all developer accounts and service credentials; evaluate migration to private package registries or implementation of dependency scanning with provenance verification.

Impact

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.

Patches

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.

Workarounds

No workarounds.

AnalysisAI

Supply-chain compromise of SAP's Cloud Application Programming (CAP) Node.js database packages, where trojanized versions @cap-js/sqlite@2.2.2, @cap-js/postgres@2.2.2, and @cap-js/db-service@2.10.1 were published to npm on April 29, 2026, harvesting all local credentials (npm tokens, cloud keys, SSH keys, GitHub PATs) and attempting worm-like self-propagation. Any developer or CI pipeline that installed these versions must treat every credential on the affected machine as compromised. Rated CVSS 4.0 9.3 (Critical); EPSS is low (0.03%) and it is not in CISA KEV, but the malicious code was itself actively distributed via npm — a 'mini Shai-Hulud' style attack.
