CVE-2022-25645 is a high-severity vulnerability rated 8.1/10 on the CVSS scale. 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.. EPSS estimates a 1.76% chance of exploitation in the next 30 days.
