| CVSS | 5.5 (Medium) |
|---|---|
| Publicly Published | June 22, 2022 |
| Last Updated | January 22, 2024 |
Description
The GTM Server Side plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'GTM Server Side url' field in versions up to, and including, 1.1.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with administrative capabilities to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
