CVE-2026-93753 Details
Description
Rejected reason: This CVE ID has been rejected because it does not describe a security vulnerability.
A prototype poisoning vulnerability has been identified in the deepmerge library, affecting versions 4.2.0 through 4.3.1. The issue arises in the mergeObject() function, which improperly validates keys being written to target objects. This flaw allows attackers to inject properties into the prototype of the object returned by the merge operation, leading to unintended inheritance of values in applications that access these properties without checking for ownership.
Users can update to deepmerge version 4.3.1 or later, where this vulnerability has been fixed.
