CVE-2019-25146
The DELUCKS SEO plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the saveSettings() function that had no capability checks in versions up to, and including, 2.1.7 due to insufficient input sanitization and output escaping.
Does this matter?
Lower severity and a low EPSS score (0.80%). Track it; it rarely justifies an emergency change on its own.
Description
The DELUCKS SEO plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the saveSettings() function that had no capability checks in versions up to, and including, 2.1.7 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute whenever a victim accesses the page.
