GHSA-x2w5-725j-gf2g Prototype Pollution in convict

• npm convict: < 6.2.3 → fixed in 6.2.3

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 References • https://www.huntr.dev/bounties/1-npm-convict/ • #384 • 3b86be087d8f14681a9c889d45da7fe3ad9cd880 • 1ea0ab19c5208f66509e1c43b0d0f21c1fd29b75 For more information If you have any questions or comments about this advisory: add your question as a comment in #384
