Reflected XSS via unescaped contest query parameter
Published Apr 17, 2025 · Updated May 12, 2026
Reflected XSS in TotalSuite TotalContest Lite 2.8.1 and earlier allows remote attackers to execute scripts through a crafted request. The WordPress admin contest-submission page outputs the contest query parameter into HTML without sanitization or escaping. Execution requires a privileged user, such as an administrator, to open the attacker-supplied link, bounding the impact to that user's browser session.
