CVE-2024-45429 – Advanced Custom Fields <= 6.3.5 - Authenticated Stored Cross-Site Scripting

https://notcve.org/view.php?id=CVE-2024-45429

Cross-site scripting vulnerability exists in Advanced Custom Fields versions 6.3.5 and earlier and Advanced Custom Fields Pro versions 6.3.5 and earlier. If an attacker with the 'capability' setting privilege which is set in the product settings stores an arbitrary script in the field label, the script may be executed on the web browser of the logged-in user with the same privilege as the attacker's. The Advanced Custom Fields plugin for WordPress is vulnerable to Stored Cross-Site Scripting via field groups in all versions up to, and including, 6.3.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with the 'capability' setting privilege, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. • https://jvn.jp/en/jp/JVN67963942 https://wordpress.org/plugins/advanced-custom-fields https://www.advancedcustomfields.com https://www.advancedcustomfields.com/blog/acf-6-3-6 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
