CVE-2024-13848: JAKOB42 Reaction Buttons

Medium severity, CVSS 4.8. EPSS: 0.3% chance of exploitation in the next 30 days.

The Reaction Buttons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 2.1.6 due to insufficient input sanitization and output escaping. This makes it possible for 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. This only affects multi-site installations and installations where unfiltered_html has been disabled.
