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.

axios is a promise based HTTP client for the browser and node.js. The issue occurs when passing absolute URLs rather than protocol-relative URLs to axios. Even if baseURL is set, axios sends the request to the specified absolute URL, potentially causing SSRF and credential leakage. This issue impacts both server-side and client-side usage of axios. This issue is fixed in 1.8.2.

In axios before 1.7.8, lib/helpers/isURLSameOrigin.js does not use a URL object when determining an origin, and has a potentially unwanted setAttribute('href',href) call. NOTE: some parties feel that the code change only addresses a warning message from a SAST tool and does not fix a vulnerability.
