* VotePage.php (poll option input)
* ResultPage::getPagesTab() and getErrorsTab() (user-controllable page names)
This allows attackers to inject JavaScript and compromise user sessions under certain conditions.
This issue affects Mediawiki - SecurePoll extension: from 1.39.X before 1.39.13, from 1.42.X before 1.42.7, from 1.43.X before 1.43.2.

Technical ContextAI
Cross-site scripting (XSS) allows injection of client-side scripts into web pages viewed by other users due to insufficient output encoding.
