Doc Text:
A flaw was found in Axios, a promise-based HTTP client. This vulnerability, a Prototype Pollution "Gadget" attack, allows an attacker to manipulate the `Object.prototype.validateStatus` property. By polluting this property, all HTTP error responses (such as 401, 403, or 500) are silently treated as successful responses. This can lead to a complete bypass of application-level authentication and error handling, potentially granting unauthorized access.

Description OSIDB Bzimport 2026-04-24 19:02:05 UTC 
Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, the Axios library is vulnerable to a Prototype Pollution "Gadget" attack that allows any Object.prototype pollution to silently suppress all HTTP error responses (401, 403, 500, etc.), causing them to be treated as successful responses. This completely bypasses application-level authentication and error handling. The root cause is that validateStatus is the only config property using the mergeDirectKeys merge strategy, which uses JavaScript's in operator — an operator that inherently traverses the prototype chain. When Object.prototype.validateStatus is polluted with () => true, all HTTP status codes are accepted as success. This vulnerability is fixed in 1.15.1 and 0.31.1.
