{"id":"CVE-2026-27701","state":"PUBLISHED","title":"LiveCodes vulnerable to JavaScript Injection via untrusted PR title in i18n-update-pull workflow","description":"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.
