  "details" : [ "A flaw in Node.js Permission Model enforcement allows Bypass via `process.report.writeReport()` Path Misvalidation. This can lead to confidentiality impact or bypass of the intended security boundary under affected configurations. This vulnerability affects all supported release lines: **Node.js 22**, **Node.js 24**, and **Node.js 26**.", "A flaw was found in Node.js. This vulnerability allows a bypass of the Permission Model enforcement due to path misvalidation within the `process.report.writeReport()` function. An attacker could exploit this to bypass intended security boundaries, potentially leading to unauthorized access to sensitive information or other confidentiality impacts under specific configurations." ],
  "statement" : "This flaw affects Node.js's experimental Permission Model, a security feature that restricts filesystem, network, and process access when explicitly enabled via the --permission flag. Applications running with the default Node.js configuration (Permission Model not enabled) are not affected. When enabled, insufficient path validation in process.report.writeReport() could allow code running under a restricted permission scope to write a diagnostic report to a location outside the configured allow-list, resulting in low-severity information disclosure.",
