CVE-2022-22143
Prototype Pollution in convict
Impact
### 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 `convict@6.2.3`. Users should upgrade to `convict@6.2.3`. ### 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
