Detailsinfo

A vulnerability has been found in Node.js up to 18.19.0/20.11.0/21.6.1 and classified as critical. Affected by this vulnerability is the function fetch of the component Brotli Handler. The manipulation with an unknown input leads to a resource consumption vulnerability. The CWE definition for the vulnerability is CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. As an impact it is known to affect availability. The summary by CVE is:

A vulnerability in Node.js has been identified, allowing for a Denial of Service (DoS) attack through resource exhaustion when using the fetch() function to retrieve content from an untrusted URL. The vulnerability stems from the fact that the fetch() function in Node.js always decodes Brotli, making it possible for an attacker to cause resource exhaustion when fetching content from an untrusted URL. An attacker controlling the URL passed into fetch() can exploit this vulnerability to exhaust memory, potentially leading to process termination, depending on the system configuration.
