Source description
As published by the source; long descriptions are shortened.
All versions of eact typosquatted a popular package of similar name and tracked users who had installed the incorrect package. The package uploaded information to a remote server including: name of the downloaded package, name of the intended package, the Node version and whether the process was running as sudo. There is no further compromise. Recommendation Remove the package from your dependencies and always ensure package names are typed correctly upon installation.

# Patch Next advisory brief: GHSA-pmgv-94f5-6w7w Advisory: Malicious Package in eact IDs: GHSA-pmgv-94f5-6w7w Record: https://patchnext.com/advisories/ghsa-pmgv-94f5-6w7w (revision 2, source checked 26 Oct 2026, 12:08 UTC) Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected. Severity: Critical (CVSS 9.8) Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV. Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed. ## Affected components - npm eact: affected every version ## Suggested inspection (read-only) - `npm ls eact --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`. ## Supported action No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything. ## Required regression checks - Run the test suite and a production build. - Exercise the features that depend on eact. - Repeat the inspection and confirm that only fixed versions remain installed. ## Rollback considerations - Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward. ## Unresolved questions - Which deployments run an affected version? - Exploitation status can change. Check again before lowering the priority. - Mark the work resolved only after the fixed version is verified in production. ## Sources - Verified: https://osv.dev/vulnerability/GHSA-pmgv-94f5-6w7w (OSV record GHSA-pmgv-94f5-6w7w lists affected ranges: npm eact >=0) - Verified: https://github.com/advisories/GHSA-pmgv-94f5-6w7w (GitHub-reviewed advisory GHSA-pmgv-94f5-6w7w lists affected ranges: npm eact >=0) Commands are suggestions: review each one before running it.
