Summary

Duplicate Advisory: Axios: Prototype pollution auth subfields can inject Basic auth

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-xj6q-8x83-jv6g. This link is maintained to preserve external references.

Original Description

axios versions >=1.15.2 and <1.18.0 contain prototype-pollution read-side gadgets in Basic auth subfield handling (lib/adapters/http.js and lib/helpers/resolveConfig.js). When an application is already affected by a separate prototype-pollution primitive and makes an axios request with an own auth object that omits the username and/or password properties, axios reads the inherited Object.prototype.username and Object.prototype.password values and uses them to construct an outbound 'Authorization: Basic ...' header. axios itself does not pollute prototypes. The practical impact is outbound request tampering: an attacker who controls the polluted prototype values can inject attacker-chosen Basic auth credentials or replace an existing Authorization header. Credential disclosure is only possible under additional application-specific conditions.

Severity

6.3 (Medium)
