CVE-2026-13441
CVSS v3.1
7.2
High
| Vector | AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N |
The EventPrime – Events Calendar, Bookings and Tickets plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'new event type background color' parameter in all versions up to, and including, 4.3.4.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with custom-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the plugin's Guest Submissions setting (allow submission by anonymous user) to be enabled, which allows unauthenticated attackers to submit event types via the frontend form; when that setting is disabled, exploitation requires at minimum a subscriber-level authenticated account.
