Affected packages
• npm convict: < 6.2.4 → fixed in 6.2.4
Description
Impact
• An attacker can inject attributes that are used in other components
• An attacker can override existing attributes with ones that have incompatible type, which may lead to a crash.
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.
Patches
The problem is patched in `[email protected]`. Users should upgrade to `[email protected]`.
Workarounds
No way for users to fix or remediate the vulnerability without upgrading
