How to Fix CVE-2026-46421

To remediate this vulnerability, upgrade all affected @cap js/sqlite dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

@cap-js/sqlite fixed: 2.3.0 
npm install @cap-js/sqlite@2.3.0
@cap-js/postgres fixed: 2.3.0 
npm install @cap-js/postgres@2.3.0
@cap-js/db-service fixed: 2.11.0 
npm install @cap-js/db-service@2.11.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls @cap-js/sqlite

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-46421, inspect your project dependencies using npm:

npm ls @cap-js/sqlite

Analyze the terminal output to locate any version of @cap js/sqlite in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.3.0), your application is affected.

Note: The npm ls @cap-js/sqlite command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-506: Embedded Malicious Code, where the product contains code that appears to be malicious in nature. In @cap js/sqlite, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## 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.
