Credential theft via inherited response transformer
Published Jun 11, 2026 · Updated Aug 28, 2026
Code injection in Axios 0.19.0 through 0.31.0 and 1.0.0 through 1.15.1 allows attackers to expose credentials and alter responses. mergeConfig reads an inherited Object.prototype.transformResponse value, and transformData later invokes that value with request configuration and response data. Exploitation requires earlier control of Object.prototype in the same JavaScript context; non-function values interrupt requests, while a function can read credentials and replace returned data.
