CVE-2026-8896MIR blocks and shortcodes <= 1.0.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes
Medium 6.4
In plain English
A medium-severity cross-site scripting in MIR blocks and shortcodes from mirsoftware. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 25% of all known vulnerabilities).
Official 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.
