GHSA-8699-h45g-7hm8

Concrete CMS Cross-site Scripting vulnerability

Quick fix

GHSA-8699-h45g-7hm8 — concrete5/concrete5: upgrade to the fixed version with the command below.

composer require concrete5/concrete5:^8.5.10

Details

Concrete CMS (formerly concrete5) below 8.5.10 and between 9.0.0 and 9.1.2 is vulnerable to Stored Cross-Site Scripting (XSS) in dashboard/system/express/entities/associations because Concrete CMS allows association with an entity name that doesn’t exist or, if it does exist, contains XSS since it was not properly sanitized. Remediate by updating to Concrete CMS 9.1.3+ or 8.5.10+.
