CVE-2020-36762Network attack vector

Authenticated command execution via issue-comment interpolation

Published Jul 18, 2023 · Updated Aug 4, 2024

OS command injection in ONS Digital RAS Collection Instrument 2.0.27 and earlier allows remote authenticated users to execute shell commands. The comment workflow interpolates github.event.comment.body directly into a run script, letting shell metacharacters in a /deploy issue comment alter the command. The workflow must run for a repository issue comment containing /deploy, and injected commands execute in the GitHub Actions runner context.
