CVE-2026-2950
Description
A flaw was found in Lodash. An attacker can exploit a prototype pollution vulnerability in the _.unset and _.omit functions by bypassing a security check. This bypass is achieved by providing array-wrapped path segments, which allows for the deletion of properties from built-in JavaScript prototypes such as Object.prototype. This could lead to unexpected application behavior or denial of service.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
