Vulnerability Overview

The EventPrime – Events Calendar, Bookings and Tickets plugin for WordPress is vulnerable to Reflected HTML Content Injection via the search parameter in all versions up to 3.2.0 (exclusive) due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web content in search pages if they can successfully trick a user into performing an action such as clicking on a link.

Technical Analysis

REMEDIATION: Update to version 3.2.0, or a newer patched version --- IDENTIFIER: CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')) The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
