CVE-2026-42033 - Axios: Prototype Pollution Gadgets - Response Tampering, Data Exfiltration, and Request Hijacking
CVE ID :CVE-2026-42033
Published : April 24, 2026, 5:36 p.m. | 36 minutes ago
Description :Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, when Object.prototype has been polluted by any co-dependency with keys that axios reads without a hasOwnProperty guard, an attacker can (a) silently intercept and modify every JSON response before the application sees it, or (b) fully hijack the underlying HTTP transport, gaining access to request credentials, headers, and body. The precondition is prototype pollution from a separate source in the same process. This vulnerability is fixed in 1.15.1 and 0.31.1.
Severity: 0.0 | NA
