Medium (5.4) in arena.im arena.im. EPSS 0.3% chance of exploitation in the next 30 days.
The Arena.IM – Live Blogging for real-time events plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'arena_embed_amp' shortcode in all versions up to, and including, 0.4.1 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
