    undici vulnerable to TLS certificate validation bypass via dropped connect options in BalancedPool

    undici's BalancedPool constructor passes its entire options object through an internal deep-clone that serializes and reparses the value as JSON. Because JSON cannot represent functions, any function-valued TLS option, such as a caller-supplied checkServerIde…

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

    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 …

    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 …

    CVE-2026-18149

    undici vulnerable to Denial of Service via orphaned RetryHandler response body

    undici's retry handler can leave an already-exposed response body pending forever. When a server returns a successful response that declares a Content-Length, sends only part of the body, and closes the connection, the retry handler retries the request. If th…

    undici vulnerable to Denial of Service via unbounded decompression of compressed responses

    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 lim…

    undici vulnerable to Denial of Service via WebSocketStream unclean close

    undici's experimental WebSocketStream client crashes the whole Node.js process when a remote peer closes the TCP connection without a WebSocket close handshake. On an unclean close the internal socket-close handler calls abort on the writable stream unconditi…

    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 i…

    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 ski…
