Report: CVE-2026-2950 - lodash vulnerable to Prototype Pollution via array path bypass in `_.unset` and `
CVE ID :CVE-2026-2950 Published : March 31, 2026, 7:18 p.m. | 56 minutes ago Description :Impact: Lodash versions 4.17.23 and earlier are vulnerable to prototype pollution in the _.unset and _.omit functions. The fix for (CVE-2025-13465: ) only guards against string key members, so an attacker can bypass the check by passing array-wrapped path segments. This allows deletion of properties from built-in prototypes such as Object.prototype, Number.prototype, and String.prototype. The issue permits deletion of prototype properties but does not allow overwriting their original behavior. Patches: This issue is patched in 4.18.0. Workarounds: None. Upgrade to the patched version.
