Axios is a promise based HTTP client for the browser and Node.js. From 1.0.0 to before 1.15.2, he Axios library is vulnerable to a Prototype Pollution "Gadget" attack that allows any Object.prototype pollution in the application's dependency tree to be escalated into surgical, invisible modification of all JSON API responses - including privilege escalation, balance manipulation, and authorization bypass. The default transformResponse function at lib/defaults/index.js:124 calls JSON.parse(data, this.parseReviver), where this is the merged config object. Because parseReviver is not present in Axios defaults, not validated by assertOptions, and not subject to any constraints, a polluted Object.prototype.parseReviver function is called for every key-value pair in every JSON response, allowing the attacker to selectively modify individual values while leaving the rest of the response intact. This vulnerability is fixed in 1.15.2.
AnalysisAI
Prototype pollution in Axios JSON parsing allows attackers to manipulate JSON API responses through Object.prototype pollution in the dependency tree, enabling privilege escalation, balance manipulation, and authorization bypass on applications using affected versions 1.0.0 through 1.15.1. The vulnerability exploits the parseReviver callback parameter in the default transformResponse function, which processes every key-value pair in JSON responses without validation, permitting surgical modification of individual response values while remaining invisible to the application logic.
