All versions of dset prior to 3.1.2 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 prototype. By crafting a malicious object, it is possible to bypass this check and achieve prototype pollution.
