# CVE-2026-46421: Supply chain compromise via malicious package versions (@cap-js/sqlite,  @cap-js/postgres, @cap-js/db-service)

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.5% , percentile 44: FIRST’s model estimates a 0.5% chance of exploitation activity in the next 30 days, higher than 44% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes @cap-js/sqlite (npm) = 2.2.2, fixed in 2.3.0 ; @cap-js/postgres (npm) = 2.2.2, fixed in 2.3.0 ; @cap-js/db-service (npm) = 2.10.1, fixed in 2.11.0 . Check your lockfile, including transitive dependencies.

## What it is

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.

## Affected packages

- npm `@cap-js/sqlite` = 2.2.2 → fixed: 2.3.0
- npm `@cap-js/postgres` = 2.2.2 → fixed: 2.3.0
- npm `@cap-js/db-service` = 2.10.1 → fixed: 2.11.0

## Affected products (CVE record)

- cap-js @cap-js/sqlite: = 2.2.2
- cap-js @cap-js/postgres: = 2.2.2
- @cap-js/db-service @cap-js/db-service: = 2.10.1

## Severity

- GitHub_M CVSS 4.0: 9.3 `CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.52% probability of exploitation activity in the next 30 days; percentile 44.
