Compromised GitHub Actions reactivated with May's Shai-Hulud malware still intact

GitHub Actions repositories actions-cool/issues-helper and actions-cool/maintain-one-comment, disabled in May after being compromised in the Mini Shai-Hulud supply-chain attack, were reinstated by their maintainer starting September 16 without removing the malicious code. Socket researchers found the release tags still pointed to the original tainted commit, meaning any workflow referencing those version tags resumed downloading and executing the malware payload through at least September 25.
