CVE-2026-42036: 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, when responseType: 'stream' is used, Axios returns the response stream without enforcing maxContentLength. This bypasses configured response-size limits and allows unbounded downstream consumption. 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)
