Should you act?

  • Malicious code, not a bug. If any listed version was ever installed, assume the machine and every secret on it are compromised: remove it, rotate credentials, rebuild.
  • Only if you depend on one of the packages below, directly or transitively, in a vulnerable version. Check your lockfile with cargo audit.
  • No CVE has been assigned, so it will not appear in CVE-based scanners that ignore GitHub advisories. npm audit, pip-audit and Dependabot do read GitHub advisories.
