All the vulnerabilities related to the version 6.2.3 of the package
convict vulnerable to Prototype Pollution
The main use case of Convict is for handling server-side configurations written by the admins owning the servers, and not random users. So it's unlikely that an admin would deliberately sabotage their own server. Still a situation can happen where an admin not knowledgeable about JavaScript could be tricked by an attacker into writing the malicious JavaScript code into some config files.
The problem is patched in convict@6.2.4. Users should upgrade to convict@6.2.4.
No way for users to fix or remediate the vulnerability without upgrading
