### Impact Lodash versions 4.0.0 through 4.17.22 are vulnerable to prototype pollution in the `_.unset` and `_.omit` functions. An attacker can pass crafted paths which cause Lodash to delete methods from global prototypes. The issue permits deletion of properties but does not allow overwriting their original behavior. ### Patches This issue is patched on 4.17.23.
Update lodash to 4.17.23; lodash-amd to 4.17.23; lodash-es to 4.17.23 if you use the affected versions. Test the change in a non-production environment first.

hol-guard supply-chain scanLodash has Prototype Pollution Vulnerability in `_.unset` and `_.omit` functions affects lodash (npm), lodash-amd (npm), lodash-es (npm), lodash.unset (npm). Severity is medium. ### Impact Lodash versions 4.0.0 through 4.17.22 are vulnerable to prototype pollution in the `_.unset` and `_.omit` functions. An attacker can pass crafted paths which cause Lodash to delete methods from global prototypes. The issue permits deletion of properties but does not allow overwriting their original behavior. ### Patches This issue is patched on 4.17.23.
AI coding agents often install or upgrade packages automatically in npm. A medium vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
