9.8

CVSS v3.1

Official Description

vConsole v3.15.0 was discovered to contain a prototype pollution due to incorrect key and value resolution in setOptions in core.ts.

NVD Source

Risk Analysis

vConsole contains a prototype pollution vulnerability due to improper key and value resolution in its core configuration logic. This flaw allows an attacker to manipulate object prototypes, potentially leading to arbitrary code execution or service disruption. The critical severity score highlights the significant risk posed to applications using this library.

No public exploit is currently known, and the vulnerability is not in the CISA KEV catalog. It is remotely exploitable with low complexity.

Recommended Action

Upgrade vConsole to a version that resolves the prototype pollution issue in setOptions. Developers should implement input validation to prevent malicious object modification.
