CVE-2026-42034: Axios

Medium severity, CVSS 5.3. EPSS: 0.5% chance of exploitation in the next 30 days.

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, for stream request bodies, maxBodyLength is bypassed when maxRedirects is set to 0 (native http/https transport path). Oversized streamed uploads are sent fully even when the caller sets strict body limits. This vulnerability is fixed in 1.15.1 and 0.31.1.

Affected products

• Axios Axios: before 0.31.1 (fixed in 0.31.1); from 1.0.0, before 1.15.1 (fixed in 1.15.1)
