Name of the Vulnerable Software and Affected Versions undici versions 7.0.0 through 7.29.0 undici versions 8.0.0 through 8.10.1 Description The cache interceptor incorrectly handles the caching of unsafe HTTP methods. While documentation states only safe methods are cached, the logic used to skip...

CVE-2026-85008: Insufficient Verification of Data Authenticity

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-2026-84933: Exposure of Sensitive Information to an Unauthorized Actor

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...

Linux Distros Unpatched Vulnerability : CVE-2026-84933

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 does not handle the Set-Cookie response header anywhere in its cache path, so it neither refuses to store nor strips that header. In...

Amazon Linux 2023 : nodejs24, nodejs24-devel, nodejs24-full-i18n (ALAS2023-2026-2059)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-2059 advisory. brace-expansion through 5.0.6 is vulnerable to denial of service. The expand function exhibits exponential-time complexity in the number of consecutive non-expanding '' brace groups. An attack...

Important: nodejs24

Issue Overview: brace-expansion through 5.0.6 is vulnerable to denial of service. The expand function exhibits exponential-time complexity in the number of consecutive non-expanding '' brace groups. An attacker who passes a crafted string to expand, directly or transitively, can cause significant...

undici: undici: Integrity failure due to caching of unsafe HTTP method responses

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...

Node.js Module Undici 7.x < 7.29.0 / 8.x < 8.9.0 Information Disclosure

The nodejs module Undici detected on the host is version 7.x prior to 7.29.0 or 8.x prior to 8.9.0. It is, therefore, affected by a vulnerability: - undici's cache interceptor mishandles malformed Cache-Control private directives. In undici 7.0.0 up to before 7.29.0 and 8.0.0 up to before 8.9.0, ...

CVE-2026-14643

A flaw was found in undici. The cache interceptor in undici improperly handles optional whitespace around the equals sign in no-cache or private Cache-Control directives. This vulnerability allows an attacker to bypass cache restrictions, leading to cross-user information disclosure. Specifically...

CVE-2026-13697

A flaw was found in undici. This vulnerability allows for cross-user information disclosure when malformed Cache-Control private directives cause private response bodies and headers, such as Set-Cookie data, to be stored in a shared cache and subsequently exposed to other users. Additionally, a...

GHSA-4CWX-7WF7-3272 undici vulnerable to cross-user information disclosure and parse-time crash via degenerate private cache directives

Summary Two issues in undici's cache interceptor, both fixed by the same patch on lib/util/cache.js: 1. Shared-cache disclosure: Responses with malformed qualified Cache-Control: private directives such as private="" or private="," can be incorrectly stored in the default shared cache, then serve...
