What is CVE-2023-5291?

The Blog Filter plugin for WordPress suffers from a Stored Cross-Site Scripting issue due to inadequate sanitization of user input and escaping of output. This vulnerability impacts versions up to and including 1.5.3. Authenticated attackers with contributor-level roles can exploit this risk by using the 'AWL-BlogFilter' shortcode to inject malicious web scripts into pages.
