CVE-2021-23470

Name of the Vulnerable Software and Affected Versions putil-merge versions prior to 3.8.0

Description The issue arises from the merge() function not checking the values passed into its argument, allowing an attacker to supply a malicious value by adjusting it to include the constructor property. This vulnerability is a result of an incomplete fix.

Recommendations For versions prior to 3.8.0, update to version 3.8.0 or later to resolve the issue. As a temporary workaround, consider disabling the merge() function until a patch is available. Restrict access to the merge() function to minimize the risk of exploitation. Avoid using the constructor property in the affected function until the issue is resolved.
