FKIE_CVE-2026-63187

Vulnerability from fkie_nvd - Published: 2026-08-19 20:17 - Updated: 2026-08-25 14:16
Severity
6.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L
Summary
Logto is the modern, open-source auth infrastructure for SaaS and AI apps. From 1.40.1 until 1.41.0, Logto's .github/workflows/commitlint.yml directly interpolated github.event.pull_request.title into the Commitlint on PR title step's inline echo command before piping the title to npx commitlint. A pull request title containing a single quote could terminate the echo string and append arbitrary shell commands on the GitHub Actions runner. The pull_request trigger used a read-only GITHUB_TOKEN and did not expose repository secrets, but injected commands could alter or disrupt the ephemeral workflow execution. This issue is fixed in version 1.41.0.
