Detailed vulnerability description
The vulnerability allows a remote attacker to perform server-side request forgery against local services through a configured proxy.
The vulnerability exists due to permissive list of allowed inputs in lib/helpers/shouldBypassProxy.js when evaluating NO_PROXY rules for requests to 0.0.0.0 in the Node.js HTTP adapter. A remote attacker can supply a crafted request URL or redirect target to perform server-side request forgery against local services through a configured proxy.
Exploitation requires axios to run in Node.js with environment proxy variables enabled, attacker-controlled input to influence the request URL or redirect target, and a proxy that can reach or relay 0.0.0.0 to local destinations.
