Summary
Important: nodejs22 security 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):

  • nodejs: Node.js: Unauthorized filesystem access due to Permission Model enforcement flaw (CVE-2026-58043)
  • nodejs: Node.js: Remote memory exhaustion via HTTP/2 retained header blocks (CVE-2026-56846)
  • nodejs: Node.js: Heap-use-after-free in HTTP/2 handling can lead to denial of service (CVE-2026-56848)

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.
