CVE-2025-58754

Description

Axios is a promise based HTTP client for the browser and Node.js. When Axios prior to version 1.11.0 runs on Node.js and is given a URL with the data: scheme, it does not perform HTTP. Instead, its Node http adapter decodes the entire payload into memory (Buffer/Blob) and returns a synthetic 200 response. This path ignores maxContentLength / maxBodyLength (which only protect HTTP responses), so an attacker can supply a very large data: URI and cause the process to allocate unbounded memory and crash (DoS), even if the caller requested responseType: 'stream'. Version 1.11.0 contains a patch for the issue.
