🚨High - deepmerge Prototype Pollution via mergeObject() (CVE-2026-93753) deepmerge <= 4.3.1 fails to validate dangerous keys in mergeObject(), allowing a crafted source object with __proto__/constructor/prototype to poison the returned object's prototype during merge. Downstream code that reads properties without own-property checks can inherit attacker-controlled values; merges of fully trusted objects are not impacted. 👉Affected: deepmerge <= 4.3.1
