What is CVE-2023-4961?

The Poptin plugin for WordPress, prior to version 1.3, contains a Stored Cross-Site Scripting vulnerability due to inadequate input sanitization and output escaping of user-supplied attributes in the 'poptin-form' shortcode. This flaw allows authenticated attackers with contributor-level or higher permissions to inject arbitrary web scripts into pages. These scripts could execute whenever an unsuspecting user accesses a page containing the modified form, potentially compromising user data and site integrity.
