CVE-2026-8896
Description
The MIR blocks and shortcodes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'title' attribute (and other attributes such as 'ready_animation_text') of the 'msc_stats' shortcode in versions up to, and including, 1.0.0. This is due to insufficient input sanitization and output escaping on user supplied shortcode attributes inside the msc_stats() rendering function. 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.
Summary dbcve.org
The MIR blocks and shortcodes WordPress plugin up to version 1.0.0 suffers from a stored XSS vulnerability in the msc_stats shortcode. Authenticated attackers with contributor-level access can inject malicious JavaScript via unsanitized shortcode attributes (title, ready_animation_text, etc.) that persist in page content and execute when users view affected pages.
Mitigation
Apply input sanitization (sanitize_text_field, esc_attr) to all shortcode attributes before output and ensure proper output escaping (esc_html, esc_attr) in the msc_stats() rendering function. Update to any version beyond 1.0.0 if available.
