CVE-2022-25645 is a medium-severity flaw (CVSS 6.5) affecting dset. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

All versions of package dset are vulnerable to Prototype Pollution via 'dset/merge' mode, as the dset function checks for prototype pollution by validating if the top-level path contains __proto__, constructor or protorype. By crafting a malicious object, it is possible to bypass this check and achieve prototype pollution.
