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-auditand Dependabot do read GitHub advisories.
