CVE-2020-5294Network attack vector

Authenticated script execution via unvalidated social URLs

Published Apr 16, 2020 · Updated Aug 4, 2024

Cross-site scripting in PrestaShop Social media follow links before 2.1.0 allows remote authenticated users to run script in a visitor's browser. The module's getContent path stored social-network field values without validating them as URLs, and the storefront template placed each value in an href attribute. A back-office user must save a crafted value and a visitor must click the resulting social link, exposing the visitor's browser context.
