VCID-8ruv-6g79-c7ex fetch(url) leads to a memory leak in undici ### Impact Calling `fetch(url)` and not consuming the incoming body ((or consuming it very slowing) will lead to a memory leak. ### Patches Patched in v6.6.1 ### Workarounds Make sure to always consume the incoming body. CVE-2024-24750
GHSA-9f24-jqhm-jfcw
VCID-rjwu-g5e6-63f2 Undici vulnerable to data leak when using response.arrayBuffer() ### Impact Depending on network and process conditions of a `fetch()` request, `response.arrayBuffer()` might include portion of memory from the Node.js process. ### Patches This has been patched in v6.19.2. ### Workarounds There are no known workaround. ### References https://github.com/nodejs/undici/issues/3337 https://github.com/nodejs/undici/issues/3328 https://github.com/nodejs/undici/pull/3338 https://github.com/nodejs/undici/commit/f979ec3204ca489abf30e7d20e9fee9ea7711d36 CVE-2024-38372
GHSA-3g92-w8c5-73pq
VCID-vdca-exd1-rfce Undici has Unbounded Memory Consumption in its DeduplicationHandler via Response Buffering that leads to DoS ## Impact This is an uncontrolled resource consumption vulnerability (CWE-400) that can lead to Denial of Service (DoS). In vulnerable Undici versions, when `interceptors.deduplicate()` is enabled, response data for deduplicated requests could be accumulated in memory for downstream handlers. An attacker-controlled or untrusted upstream endpoint can exploit this with large/chunked responses and concurrent identical requests, causing high memory usage and potential OOM process termination. Impacted users are applications that use Undici’s deduplication interceptor against endpoints that may produce large or long-lived response bodies. ## Patches The issue has been patched by changing deduplication behavior to stream response chunks to downstream handlers as they arrive (instead of full-body accumulation), and by preventing late deduplication when body streaming has already started. Users should upgrade to the first official Undici (and Node.js, where applicable) releases that include this patch. ## Workarounds If upgrading immediately is not possible: - Disable `interceptors.deduplicate()` for affected clients/routes. - Use `skipHeaderNames` with a marker header to force high-risk requests to bypass deduplication. - Avoid concurrent identical requests to untrusted endpoints that may return very large/chunked bodies. - Apply upstream/proxy response-size and timeout limits.
