How to Fix GHSA-vr6p-vq2p-6j74

To remediate this vulnerability, upgrade all affected Withdrawn Advisory dependencies to a patched release.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

likec4 fixed: Latest secure release 
npm install likec4@Latest secure release
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 likec4

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-vr6p-vq2p-6j74, inspect your project dependencies using npm:

npm ls likec4

Analyze the terminal output to locate any version of Withdrawn Advisory in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The npm ls likec4 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-502: Deserialization of Untrusted Data, where the product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid. In Withdrawn Advisory, software state validation or input boundaries are circumvented during processing.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

### Withdrawn Advisory This advisory has been withdrawn because LikeC4 isn’t impacted by CVE-2025-55182 because it doesn’t ship React. React is a peer dependency. ### Original Description LikeC4 uses React and Next.js: which contain known RCE vulnerabilities, as seen in CVE-2025-55182. [2025-12-15] Edit: the last fixes published by React were not thorough, a new set of fix releases completes the mitigation; see https://react.dev/blog/2025/12/11/denial-of-service-and-source-code-exposure-in-react-server-components
