 "title": "CP Multi View Events Calendar <= 1.4.42 - Unauthenticated Stored Cross-Site Scripting via Event Title",
 "description": "The CP Multi View Events Calendar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the event title in all versions up to, and including, 1.4.42. Titles are stored with sanitize_text_field(), which keeps quote characters. The client-side htmlEscape() helper in jquery.calendar.js removes some tags and event-handler attributes but does not encode quotes, and the calendar templates place the title inside HTML attributes (title1=\"${title}\", title=\"${title}\"). This makes it possible for authenticated attackers with Subscriber-level access and above, and for unauthenticated attackers when a calendar view has public editing enabled, to inject arbitrary web scripts that run whenever a user views the calendar.",
