Security Advisory
CVE-2026-8898
CVE vulnerability detail — eXtreme Datacenter Security Operations
Description
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.
