Server-Side Request Forgery (SSRF) vulnerability in SEOPress allows Server Side Request Forgery.

This issue affects SEOPress: from n/a through 10.1.

The SEOPress WordPress plugin before 7.3 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Cross-Site Scripting attacks even when unfilteredhtml is disallowed

The SEOPress WordPress plugin before 6.5.0.3 unserializes user input provided via the settings, which could allow high-privilege users such as admin to perform PHP Object Injection when a suitable gadget is present.

The SEOPress WordPress plugin is vulnerable to Stored Cross-Site-Scripting via the processPut function found in the ~/src/Actions/Api/TitleDescriptionMeta.php file which allows authenticated attackers to inject arbitrary web scripts, in versions 5.0.0 - 5.0.3.
