CVE-2026-58043: A flaw in Node.js Permission Model enforcement can over-grant filesystem access across radix-tree prefix boundaries.

HighCVSS 8.4 · v3.1—Proof of concept Fix available

Noroxi assessment

Priority: Monitor (action score 33/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.13% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: azl3 nodejs 24.17.0-1 on Azure Linux 3.0 24.18.1-1.

Low priority for now. Upgrade to azl3 nodejs 24.17.0-1 on Azure Linux 3.0 24.18.1-1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

A flaw in Node.js Permission Model enforcement can over-grant filesystem access across radix-tree prefix boundaries. Under `--permission`, an attacker who is granted access to one path can abuse boundary handling to read from or write to paths outside the intended filesystem allowlist. This vulnerability affects Node.js **main**, **22.x**, **24.x**, and **26.x**.
