CVE-2026-85063

Description

A flaw was found in node-csv, specifically within its csv-parse component. When configured with columns and group_columns_by_name options, a remote attacker can craft a malicious CSV header to manipulate the proto property. This allows the injection of attacker-controlled values into the parsed record's prototype, leading to information disclosure. This vulnerability can also affect property enumeration and type or shape checks in applications processing the record.

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).

The following CVSS metrics and score provided are preliminary and subject to review.
