hol-guard supply-chain scanMJML allows mj-include directory traversal due to an incomplete fix for CVE-2020-12827 affects mjml (npm). Severity is medium. MJML before 5.0.0-alpha.9 allows mj-include directory traversal to test file existence and (in the type="css" case) read files. NOTE: this issue exists because of an incomplete fix for CVE-2020-12827.
AI coding agents often install or upgrade packages automatically in npm. A medium vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
