seo plugin by squirrly seo squirrly	`< 12.3.20`	`12.3.20`

Description

The SEO Plugin by Squirrly SEO plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘url’ parameter in all versions up to, and including, 12.3.19 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. CVE-2024-43286 appears to be a duplicate of this issue.
