CVE-2023-2436
The Blog-in-Blog plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'blog_in_blog' shortcode in versions up to, and including, 2.0.0 due to insufficient input sanitization and output escaping on user supplied attributes.
Does this matter?
Lower severity and a low EPSS score (0.48%). Track it; it rarely justifies an emergency change on its own.
Description
The Blog-in-Blog plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'blog_in_blog' shortcode in versions up to, and including, 2.0.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with editor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
