CVE-2026-27701

LiveCode is an open-source, client-side code playground.

Published Feb 25, 2026 · updated Jun 17, 2026

LiveCode is an open-source, client-side code playground. Prior to commit e151c64c2bd80d2d53ac1333f1df9429fe6a1a11, LiveCode's GitHub Actions workflow is vulnerable to JavaScript injection. The title of the Pull Request associated with the triggering issue comment is interpolated directly into a JavaScript block using a GitHub Actions template expression. An attacker who opens a PR with a crafted title can inject arbitrary JavaScript that executes with the privileges of the CI bot token ( / ), enabling exfiltration of repository secrets and unauthorized GitHub API operations. Commit e151c64c2bd80d2d53ac1333f1df9429fe6a1a11 fixes the issue.
