Script execution via unencoded emoji attributes
Published Aug 21, 2026 · Updated Aug 21, 2026
Cross-site scripting in DiscordChatExporter before 2.47.2 allows attackers to execute script through crafted emoji metadata in HTML exports. VisitEmojiAsync inserts emoji.Name and emoji.Code directly into alt and title attributes without HTML entity encoding. Exploitation requires tampered offline input or relaxed upstream validation and a user opening the generated HTML file.
