GHSA-vr6p-vq2p-6j74: LikeC4 has RCE through vulnerable React and Next.js versions
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
Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
