What an attacker can do

An attacker can publish a benign-looking frontend repo whose config.json points via auto_map to a separate malicious backend repo; loading the frontend will silently run the backend’s code on the victim host. Vendor/CNA’s CVSS 3.1 assessment (base score 7.1/10) rates confidentiality, integrity and availability impact as high. NVD’s CVSS 3.1 assessment (base score 8.8/10) rates confidentiality, integrity and availability impact as high.
