SUSE CVE-2026-84947

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...

SUSE 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

A flaw was found in undici. The cache interceptor incorrectly caches responses to unsafe HTTP methods, such as POST, PUT, or DELETE. A remote attacker can exploit this by providing a cacheable response, leading to subsequent state-changing requests being served from a stale cache entry without...

CVE-2026-18540

A flaw was found in undici. An attacker-controlled upstream server can exploit a vulnerability in the retry interceptor, which incorrectly appends data to a ranged retry response. This can cause the response body to be longer than the Content-Length observed by the application. Consequently, an...

Uncaught Exception

Overview Affected versions of this package are vulnerable to Uncaught Exception through the HTTP/2 header processing path in internal/transport/http2server.go and internal/xds/server/routing.go. An attacker can crash the server by sending a gRPC request that omits both the :authority and Host...

SUSE CVE-2026-18540

undici's retry interceptor can append the body of a ranged retry response to bytes already delivered from an earlier partial response while still presenting the original response's status and headers. This happens when an upstream server delivers part of a body without a trustworthy resume...

Linux Distros Unpatched Vulnerability : CVE-2026-85008

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - 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 t...

Insufficient Verification of Data Authenticity

Overview undici is an An HTTP/1.1 client, written from scratch for Node.js Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity in the interceptors.cache interceptor, whose skip-list construction subtracts the configured methods from the safe-method s...

Use of Persistent Cookies Containing Sensitive Information

Overview org.webjars.npm:undici is an An HTTP/1.1 client, written from scratch for Node.js Affected versions of this package are vulnerable to Use of Persistent Cookies Containing Sensitive Information in the interceptors.cache interceptor's shared-cache mode type: 'shared', which stores response...

HTTP Request Smuggling

Overview undici is an An HTTP/1.1 client, written from scratch for Node.js Affected versions of this package are vulnerable to HTTP Request Smuggling in the interceptors.retry interceptor, which resumes a partial response and appends the resumed bytes to an already-delivered body, so the delivere...

Allocation of Resources Without Limits or Throttling

Overview undici is an An HTTP/1.1 client, written from scratch for Node.js Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the interceptors.decompress interceptor, which caps the decompression chain at 5 layers but does not bound the tot...

Overview org.webjars.npm:undici is an An HTTP/1.1 client, written from scratch for Node.js Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the interceptors.decompress interceptor, which caps the decompression chain at 5 layers but does n...

CVE-2026-84947

A flaw was found in undici, a Node.js HTTP/1.1 client. When the dump interceptor processes oversized chunked responses that do not declare a Content-Length, it prematurely signals completion. This causes the application to receive an incomplete or empty response body, while the network connection...

CVE-2026-84890

A flaw was found in undici. The decompress interceptor in undici processes compressed response bodies based on the untrusted Content-Encoding header. A remote attacker can exploit this by sending a small, specially crafted compressed payload, known as a 'compression bomb,' which expands...

DEBIAN-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...
