A weakness has been identified in apidevtools json-schema-ref-parser up to 15.3.5. This impacts the function Refs.set/Pointer.set in the library lib/pointer.ts. Executing a manipulation can lead to improperly controlled modification of object prototype attributes. The attack can be launched remotely. Upgrading to version 15.3.6 will fix this issue. This patch is called a786bc6afc3674f650496472ee93d5cf74c4bd84. It is suggested to upgrade the affected component.
AI Analysis
Technical Summary
The vulnerability CVE-2026-15195 affects apidevtools json-schema-ref-parser versions 15.3.0 through 15.3.5. It arises from insufficient control over modifications to object prototype attributes in the functions Refs.set and Pointer.set within lib/pointer.ts. This can lead to unintended prototype pollution, which attackers can exploit remotely. The problem is resolved by upgrading to version 15.3.6, which includes a patch identified by commit a786bc6afc3674f650496472ee93d5cf74c4bd84.
Potential Impact
Successful exploitation allows remote attackers to manipulate object prototype attributes improperly, potentially leading to prototype pollution-related issues. The CVSS 4.0 score of 5.3 indicates a medium impact with network attack vector, low complexity, no user interaction, and limited confidentiality, integrity, and availability impacts.
Mitigation Recommendations
Upgrade the apidevtools json-schema-ref-parser library to version 15.3.6 or later, which contains the official fix for this vulnerability. No other mitigation is indicated or required.
