Vulnerability Overview

The Contest Gallery – Upload, Vote & Sell with PayPal and Stripe plugin for WordPress is vulnerable to CSV Injection in all versions up to, and including, 27.0.3 via gallery submissions. This makes it possible for unauthenticated attackers to embed untrusted input into exported CSV files, which can result in code execution when these files are downloaded and opened on a local system with a vulnerable configuration.

Technical Analysis

REMEDIATION: Update to version 28.0.0, or a newer patched version --- IDENTIFIER: CWE-1236 (Improper Neutralization of Formula Elements in a CSV File) The product saves user-provided information into a Comma-Separated Value (CSV) file, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as a command when the file is opened by a spreadsheet product.
