Doc Text:
A flaw was found in Axios, a promise-based HTTP client. An attacker who can control the destination address of an Axios request can exploit this vulnerability. By using specific internal network addresses (within the 127.0.0.0/8 range, excluding 127.0.0.1), the attacker can completely bypass the NO_PROXY protection, potentially leading to unauthorized access or information disclosure within the network. This issue is an incomplete fix for a previous vulnerability.
