The Divi theme for WordPress suffers from a stored XSS vulnerability due to insufficient input sanitization and output escaping. Authenticated users with Author-level privileges or above can inject arbitrary web scripts into pages, which execute upon page access by other users. This vulnerability is tracked as CVE-2024-5533 and is classified under CWE-20 (Improper Input Validation). It affects all versions up to 4.25.1. The CVSS 3.1 base score is 6.4, reflecting a medium severity with network attack vector, low attack complexity, and privileges required at the Author level.

Successful exploitation allows an attacker with Author-level access or higher to inject and execute arbitrary scripts in the context of the affected website. This can lead to limited confidentiality and integrity impacts, such as session hijacking or content manipulation. There is no impact on availability reported. The vulnerability requires authenticated access, limiting the attack surface to users with elevated privileges.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Author-level and higher privileges to trusted users only. Monitor for suspicious activity related to script injection. Avoid granting unnecessary elevated permissions to reduce risk.
