Summary
Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

Vulnerabilities 15
-
High 7.7
A flaw in Node.js TLS hostname handling can cause Node.js unicode dot separator handling can lead to tls wildcard-depth…
-
High 7.5
undici WebSocket client vulnerable to denial of service via fragment count bypass
Impact: The undici WebSocket client enforces maxPayloadSize on the cumulative byte count of fragments in a message but does not enforce a limit on the number of fragments. A malicious WebSocket server can stream many small or empty continuation frames that ea…
-
High 7.5
A flaw in Node.js WebCrypto implementation can crash the process if the input of `subtle.encrypt()` is a multiple of 2G…
-
High 7.5
undici vulnerable to cross-origin request routing via SOCKS5 proxy pool reuse
Impact: When using Socks5ProxyAgent, undici reuses a single connection pool across different origins without verifying that the pool's origin matches the requested origin. All requests are dispatched through the pool connected to the first origin, regardless …
-
High 7.4
undici vulnerable to TLS certificate validation bypass via dropped requestTls in SOCKS5 ProxyAgent
Impact: undici's ProxyAgent silently drops the requestTls option when configured with a SOCKS5 proxy URI (socks5:// or socks://). The target HTTPS connection through the SOCKS5 tunnel falls back to Node's default trust store, ignoring user-configured ca, cert…
-
Medium 5.9
A flaw in Node.js proxy tunnel error handling could expose proxy credentials in `ERR_PROXY_TUNNEL` error messages. When…
-
Medium 5.9
undici vulnerable to cross-user information disclosure via shared cache whitespace bypass
Impact: Undici's cache interceptor incorrectly classifies some responses as cacheable when the upstream Cache-Control header uses whitespace-padded qualified private or no-cache field names such as private=" authorization" or no-cache="\tauthorization". The p…

Medium 5.6
A flaw in Node.js TLS hostname handling can cause Embedded-nul hostnames can lead to silent authority rebinding due to …

Medium 5.3
ip-address: XSS in Address6 HTML-emitting methods
ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. Prior to 10.1.1, Address6.group() and Address6.link() do not HTML-escape attacker-controlled content before embedding it in the HTML strings they return, and AddressEr…

A flaw in Node.js HTTP/2 client allows a server to send an unlimited number of ORIGIN frames, which could lead to an Ou…

Medium 4.2
A inconsistency in Node.js hostname matching can cause a trust-policy bypass in multi-context mTLS setups. This vulnera…
-
Low 3.7
undici vulnerable to Set-Cookie SameSite attribute downgrade via permissive substring matching
Impact: When undici parses a Set-Cookie header, it accepts any SameSite attribute value that contains Strict, Lax, or None as a substring, rather than the case-insensitive exact match specified by RFC 6265. Non-spec values are silently mapped to one of the th…
-
Low 3.7
undici vulnerable to HTTP response queue poisoning via keep-alive socket reuse
Impact: Undici's HTTP/1.1 client is vulnerable to response queue poisoning on reused keep-alive sockets. An attacker-controlled upstream server can inject an unsolicited HTTP/1.1 response onto an idle socket after a request completes. When the client dispatch…

Low 3.3
A flaw in Node.js Permission API can cause a file metadata to be modified even on a path that was set as read-only with…
