CVE-2026-27701
LiveCode is an open-source, client-side code playground. Prior to commit e151c64c2bd80d2d53ac1333f1df9429fe6a1a11, LiveCode's i18n-update-pull 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 actions/github-script 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 (CI_APP_ID / CI_APP_PRIVATE_KEY), enabling exfiltration of repository secrets and unauthorized GitHub API operations. Commit e151c64c2bd80d2d53ac1333f1df9429fe6a1a11 fixes the issue.
