Users should monitor the vendor's advisory for updates. Until a fix is available, restrict contributor-level access to trusted users only and consider disabling or limiting use of the affected parameter.
Description
The Eventin WordPress plugin (up to version 4.1.23) contains a stored cross-site scripting (XSS) vulnerability via the 'etn_shedule_objective' schedule_slot parameter. Authenticated users with contributor-level or higher privileges can inject malicious scripts that execute when other users view the affected pages. This vulnerability arises from insufficient input sanitization and output escaping.
