CVE-2024-0688

Name of the Vulnerable Software and Affected Versions WebSub (FKA. PubSubHubbub) plugin for WordPress versions up to, and including, 3.1.4

Description The issue is related to Stored Cross-Site Scripting via plugin settings due to insufficient input sanitization and output escaping. This allows authenticated attackers with administrator-level permissions and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 3.1.4, update to a version higher than 3.1.4 to resolve the issue. As a temporary workaround, consider restricting access to plugin settings to minimize the risk of exploitation.
