Denial of Service in Axios mergeConfig via __proto__ config object
Axios contains a denial-of-service vulnerability in the mergeConfig function prior to versions 0.30.3 and 1.13.5. When mergeConfig processes a configuration object that has proto as an own property, such as an object produced from attacker-controlled JSON via JSON.parse(), it can throw a TypeError and crash the application. The issue arises during merging of configuration objects supplied to Axios request/config APIs. In affected deployments, an attacker can supply a crafted object like {"proto":{"x":1}} that is later passed into Axios configuration handling, causing the Node.js process to terminate.
