RHSA-2026:98619: Important: nodejs26 security, bug fix, and enhancement update

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): nodejs: Node.js: Permission Model bypass via process.report.writeReport() path misvalidation (CVE-2026-48617) nodejs: Node.js HTTP Agent: Information disclosure due to premature response acceptance (CVE-2026-48931) 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: Local server can be started without network permission via Permission API flaw (CVE-2026-48936) nodejs: Node.js: Authentication bypass due to TLS hostname handling and unicode dot separator mismatch (CVE-2026-48618) undici: undici: Information disclosure and Denial of Service via malformed Cache-Control directives (CVE-2026-13697) nodejs: Node.js: Unauthorized filesystem access due to Permission Model enforcement flaw (CVE-2026-58043) nodejs: HTTPS Agent TLS session reuse skips hostname verification (CVE-2026-58040) nodejs: Node.js: Permission Model flaw allows trace logs to bypass filesystem write restrictions (CVE-2026-56847) nodejs: Node.js: mTLS client identities can be reused due to HTTPS Agent connection flaw (CVE-2026-56850) nodejs: Information disclosure due to improper permission enforcement (CVE-2026-58039) nodejs: Node.js: Request smuggling via HTTP client header truncation (CVE-2026-58044) nodejs: Node.js: Denial of Service via DNS responses with excessive A records (CVE-2026-58042) nodejs: Node.js: Denial of Service vulnerability (CVE-2026-58045) nodejs: Node.js node:sqlite: Unintended data modification due to stale statement iterator (CVE-2026-58041) nodejs: Node.js: Heap-use-after-free in HTTP/2 handling can lead to denial of service (CVE-2026-56848) brace-expansion: brace-expansion: Denial of Service via uncontrolled recursion in nested brace patterns (CVE-2026-102278) brace-expansion: brace-expansion: Denial of Service via stack exhaustion from crafted brace patterns (CVE-2026-102276) undici: undici: Denial of Service via unhandled stream error on excessive content encodings (CVE-2026-109869) undici: undici: Denial of Service via TLS renegotiation with mismatched certificate (CVE-2026-87018) undici: undici: Certificate validation bypass via dropped TLS options in Agent (CVE-2026-109383) undici: undici: Cache poisoning and information disclosure via improper cross-origin redirect caching (CVE-2026-109829) nodejs: nodejs: TLS certificate hostname bypass via fullwidth-digit IP hostnames (CVE-2026-105483) nodejs: nodejs: TLS certificate hostname bypass via non-canonical IP hostnames (CVE-2026-106069) nodejs: nodejs: dns.resolve truncates hostnames containing a NUL character (CVE-2026-105482) Bug Fix(es) and Enhancement(s): nodejs26: Rebase to the latest Node.js 26 release [rhel-10.3.z] (JIRA:RHEL-295502) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
