CVE-2024-3021

Name of the Vulnerable Software and Affected Versions Mhr Post Ticker plugin for WordPress versions up to, and including, 1.1

Description The issue is related to Stored Cross-Site Scripting via the Header Title value due to insufficient input sanitization and output escaping. This allows authenticated attackers with administrator-level access to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The issue only affects multi-site installations and installations where unfiltered html has been disabled.

Recommendations For versions up to, and including, 1.1, update to a version that addresses the insufficient input sanitization and output escaping issue to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting administrator-level access and monitoring page content for injected scripts.
