CVE-2022-4836 – Breadcrumb < 1.5.33 - Contributor+ Stored XSS via Shortcode

https://notcve.org/view.php?id=CVE-2022-4836

The Breadcrumb WordPress plugin before 1.5.33 does not validate and escape some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks which could be used against high privilege users such as admins. The Breadcrumb plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'breadcrumb_themes' (within in the 'breadcrumb_display' function) in versions up to, and including, 1.5.32 due to insufficient input sanitization and output escaping. This makes it possible for contributor-level attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. • https://wpscan.com/vulnerability/e9a228dc-d32e-4918-898d-4d7af4662a14 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
