Researchers at Praetorian discovered a vulnerability in GitHub's CodeQL system that allowed attackers to execute arbitrary code during the build process of CodeQL queries. This was possible because CodeQL inadvertently exposed secrets within its build environment, which a malicious actor could exploit by submitting a specially crafted query. This constituted a supply chain attack, as any repository using the compromised query would unknowingly execute the malicious code. Praetorian responsibly disclosed the vulnerability to GitHub, who promptly patched the issue and implemented additional security measures to prevent similar attacks in the future.
