CVE-2026-101902: Axios

Medium severity, CVSS 6.9. EPSS: 0.4% chance of exploitation in the next 30 days.

Axios is a promise-based HTTP client for the browser and Node.js. From 0.27.2 until 0.34.0 and 1.20.0, Axios default-instance requests that omit an explicit method can read an inherited method value from Object.prototype. If another vulnerability in the same process pollutes Object.prototype.method, calls such as axios.request({ url }) and axios({ url }) can send a state-changing HTTP method instead of the expected default GET. Axios does not create the prototype pollution source. This is a read-side gadget in axios request dispatch. This issue is fixed in version 0.34.0 and 1.20.0.

Affected products

• Axios Axios: from 1.0.0, before 1.20.0 (fixed in 1.20.0); from 0.27.2, before 0.34.0 (fixed in 0.34.0)
