CVE-2026-2581

A flaw was found in Undici. When the `interceptors.deduplicate()` feature is enabled, response data for deduplicated requests can accumulate in memory. A remote attacker, by sending large or chunked responses and concurrent identical requests from an untrusted endpoint, can exploit this uncontrolled resource consumption. This leads to high memory usage and potential Out-Of-Memory (OOM) process termination, resulting in a Denial of Service (DoS) for the application.
