CVE-2026-8898

Descripción

The Events In City plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the -org-events- shortcode in versions up to, and including, 3.0. This is due to insufficient input sanitization and output escaping on user supplied attributes (such as -organizer_id-, -width-, -height-, -transparency-, -header-, -border-, and -layout-) in the org_event_scode() function. The attribute values are concatenated directly into HTML attributes without esc_attr(). 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.
