Low risk8th percentile - higher than 8% of all known CVEs
Summary
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.
Risk Assessment
Authenticated attackers with contributor-level access or above can inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page, potentially leading to session theft, redirects, or other malicious actions.
Recommendation
Immediately update the MIR blocks and shortcodes plugin to the latest available version that fixes this vulnerability. If no update is available, temporarily disable the plugin or remove the 'msc_stats' shortcode from page content.
