  "details" : [ "Undici is an HTTP/1.1 client for Node.js. Prior to 7.18.0 and 6.23.0, the number of links in the decompression chain is unbounded and the default maxHeaderSize allows a malicious server to insert thousands compression steps leading to high CPU usage and excessive memory allocation. This vulnerability is fixed in 7.18.0 and 6.23.0.", "A flaw was found in Undici, an HTTP/1.1 client for Node.js. A remote attacker could exploit this vulnerability by sending a specially crafted HTTP response with an unbounded number of links in the decompression chain. This could lead to high CPU usage and excessive memory allocation, resulting in a Denial of Service (DoS) for the affected system." ],
  "statement" : "This vulnerability is rated Low for Red Hat products. The flaw in Undici, an HTTP/1.1 client for Node.js, allows a remote malicious server to trigger a Denial of Service by sending a specially crafted HTTP response with excessive decompression steps. This can lead to high CPU usage and memory allocation on the client system. Red Hat products utilizing Undici that connect to untrusted external HTTP servers are potentially affected.",
