CVE-2026-84890

undici's decompress interceptor decompresses response bodies according to the untrusted Content-Encoding header. While the number of content-encoding layers is capped, the total decompressed output size is unbounded and there is no configuration option to limit it. A malicious or faulty upstream...

undici's cache interceptor does not handle the Set-Cookie response header anywhere in its cache path, so it neither refuses to store nor strips that header. In shared cache mode, which is the default, an otherwise cacheable response that carries a Set-Cookie header, for example one marked with a...

CVE-2026-84933 undici vulnerable to cross-user cookie disclosure via Set-Cookie caching in shared caches

undici's cache interceptor does not handle the Set-Cookie response header anywhere in its cache path, so it neither refuses to store nor strips that header. In shared cache mode, which is the default, an otherwise cacheable response that carries a Set-Cookie header, for example one marked with a...

CVE-2026-84933

undici (Node.js HTTP client) has a vulnerability in its cache interceptor that fails to handle the Set-Cookie response header in its cache path—neither refusing to store nor stripping it. In shared cache mode (the default), a cacheable response carrying a Set-Cookie header is stored and re-served...

CVE-2026-84947

CVE-2026-84947 affects undici (Node.js HTTP client), specifically its dump interceptor . When a chunked response (no Content-Length) exceeds the configurable maximum body size, the interceptor signals completion early without pausing or aborting the request. The underlying parser then delivers a ...

CVE-2026-84947 undici vulnerable to response truncation via oversized chunked responses in the dump interceptor

undici's dump interceptor reads and discards a response body up to a configurable maximum size. When a response declares a Content-Length that exceeds the maximum, the interceptor aborts cleanly, but when a response has no Content-Length and is chunked, the interceptor instead signals completion...

CVE-2026-85008

undici's cache interceptor documents that only safe HTTP methods are cached, but its logic to skip caching is built by subtracting the configured methods from the set of safe methods, so an unsafe method such as POST, PUT, or DELETE is never placed in the skip list and instead falls through to th...

CVE-2026-85008 undici vulnerable to caching and replay of unsafe HTTP method responses

undici's cache interceptor documents that only safe HTTP methods are cached, but its logic to skip caching is built by subtracting the configured methods from the set of safe methods, so an unsafe method such as POST, PUT, or DELETE is never placed in the skip list and instead falls through to th...

CVE-2026-85008

undici (the Node.js HTTP client library) contains a caching integrity flaw in its cache interceptor . The skip-list logic is built by subtracting configured methods from the set of safe methods, so unsafe methods (POST, PUT, DELETE) are never added to the skip list and fall through to the full ca...

undici 8.10.0 omits the destination origin from the cache and request-deduplication keys when the cache or deduplicate interceptor is composed directly onto a Client or Pool. Because the internal cache key falls back to an empty origin string, a cacheable or in-flight response from one upstream...

CVE-2026-85152 undici vulnerable to cross-origin cache poisoning via missing origin isolation in interceptors
