Summary
Important: nodejs24 security, bug fix, and enhancement update
Details
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.
Security Fix(es):
- ip-address: ip-address: Cross-site scripting via improper HTML escaping of untrusted input (CVE-2026-42338)
- undici: undici: Denial of Service due to unbounded memory growth via WebSocket frames (CVE-2026-12151)
- undici: Undici: Information disclosure due to improper cache-control header parsing (CVE-2026-9678)
- undici: Undici: Response queue poisoning on reused keep-alive sockets can lead to incorrect response delivery. (CVE-2026-6733)
- undici: undici: Weakening of cookie SameSite policy due to incorrect parsing of Set-Cookie header (CVE-2026-11525)
- undici: undici: Man-in-the-Middle attack via ignored TLS options with SOCKS5 proxy (CVE-2026-9697)
- undici: undici: Information disclosure and data integrity issues due to incorrect Socks5ProxyAgent connection routing (CVE-2026-6734)
- nodejs: Node.js: Denial of Service via unlimited HTTP/2 ORIGIN frames (CVE-2026-48619)
- nodejs: Node.js: Silent authority rebinding due to embedded-nul hostnames in TLS handling (CVE-2026-48930)
- nodejs: Node.js: Unauthorized file metadata modification (CVE-2026-48935)
- nodejs: Node.js WebCrypto: Denial of Service via large input to subtle.encrypt() (CVE-2026-48933)
- nodejs: Node.js: Certification validation bypass in TLS host verification (CVE-2026-48934)
- Node.js: Node.js: Trust-policy bypass due to hostname matching inconsistency (CVE-2026-48928)
- nodejs: Node.js: Information disclosure of proxy credentials via proxy tunnel error handling (CVE-2026-48615)
- nodejs: Node.js: Authentication bypass due to TLS hostname handling and unicode dot separator mismatch (CVE-2026-48618)
Bug Fix(es) and Enhancement(s):
- nodejs24: Rebase to the latest Node.js 24 release [almalinux-10.2.z] (JIRA:AlmaLinux-186582)

Title
undici vulnerable to Set-Cookie SameSite attribute downgrade via permissive substring matching
Summary
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 three standard tokens. For example, SameSite=NoneOfYourBusiness is parsed as None (the most permissive setting), and SameSite=StrictLax is parsed as Lax (a downgrade from Strict).
Affected applications are those that consume Set-Cookie headers from server responses (for example via undici's fetch or proxy code paths) and then forward or rely on the parsed sameSite attribute. A malicious or non-compliant server can coerce the consumer's view of a cookie's SameSite policy to a weaker value, silently degrading the SameSite enforcement the cookie is supposed to provide.
This was introduced in undici 5.15.0 when the cookies feature was added.
Patches:
Upgrade to undici v6.26.0, v7.28.0 or v8.5.0.
Workarounds:
After parsing a Set-Cookie header, validate that the resulting sameSite attribute is one of 'Strict', 'Lax', or 'None' (exact, case-insensitive) before forwarding or relying on it.

Title
undici WebSocket client vulnerable to denial of service via fragment count bypass
Summary
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 each pass per-frame and cumulative-size validation, collectively causing unbounded memory growth in the client process. The result is memory exhaustion and a denial of service.
Affected applications are those using the undici WebSocket client (new WebSocket(...)) or the WebSocketStream API that can be induced to connect to an attacker-controlled or compromised WebSocket endpoint.
All releases starting at undici 6.17.0 are affected.
Patches: Upgrade to undici >= 6.26.0, >= 7.28.0, or >= 8.5.0. Workarounds:
No workaround is available. The fix must be applied through an upgrade.

CVE-2026-42338 (GCVE-0-2026-42338)
Vulnerability from cvelistv5 – Published: 2026-05-12 19:43 – Updated: 2026-07-07 12:05

Title
ip-address: XSS in Address6 HTML-emitting methods
Summary
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 AddressError.parseMessage (emitted by the Address6 constructor for invalid input) can contain unescaped attacker-controlled content in one branch. An application that (1) passes untrusted input to Address6 and (2) renders the output of these methods, or the thrown error's parseMessage, as HTML (e.g. via innerHTML) is vulnerable to cross-site scripting. This vulnerability is fixed in 10.1.1.
Severity
