Stored XSS via unsanitized poll comments
Published Aug 1, 2024 · Updated Apr 28, 2026
Stored XSS in LiquidPoll – Advanced Polls for Creators and Brands 3.3.77 and earlier allows remote attackers to inject scripts via poll comments. The poll-comment path accepts untrusted comment content without sufficient input sanitization and later renders it without adequate output escaping. No authentication is required; injected scripts execute in the browser whenever a user opens an affected page, enabling actions within that user's session.
