Для пакета nodejs 24.12.0 найдены CVE-кандидаты по данным NVD/CPE: CVE-2025-55130, CVE-2025-59465, CVE-2025-59466, CVE-2026-21637. Требуется triage security-team.

Проверить применимость CVE к сборке НАЙС.ОС, сопоставить с upstream/vendor advisory, определить статус affected/fixed/not_affected и при необходимости подготовить обновление пакета.

Рекомендуемое действие: needs_triage

Подсказка по целевой версии: -

Проверки: Проверить сборку RPM, обновление пакета, совместимость зависимостей, service/CLI smoke tests и регрессионные сценарии по классу пакета.

Риски: Автоматическое совпадение NVD/CPE не является финальным вердиктом по НАЙС.ОС.

Descriptions

CVE-2025-55130

A flaw in Node.js’s Permissions model allows attackers to bypass --allow-fs-read and --allow-fs-write restrictions using crafted relative symlink paths. By chaining directories and symlinks, a script granted access only to the current directory can escape the allowed path and read sensitive files. This breaks the expected isolation guarantees and enables arbitrary file read/write, leading to potential system compromise.
This vulnerability affects users of the permission model on Node.js v20, v22, v24, and v25.

CVE-2025-59465

A malformed HTTP/2 HEADERS frame with oversized, invalid HPACK data can cause Node.js to crash by triggering an unhandled TLSSocket error ECONNRESET. Instead of safely closing the connection, the process crashes, enabling a remote denial of service. This primarily affects applications that do not attach explicit error handlers to secure sockets, for example:

server.on('secureConnection', socket => {
  socket.on('error', err => {
    console.log(err)
  })
})

CVE-2025-59466

We have identified a bug in Node.js error handling where "Maximum call stack size exceeded" errors become uncatchable when async_hooks.createHook() is enabled. Instead of reaching process.on('uncaughtException'), the process terminates, making the crash unrecoverable. Applications that rely on AsyncLocalStorage (v22, v20) or async_hooks.createHook() (v24, v22, v20) become vulnerable to denial-of-service crashes triggered by deep recursion under specific conditions.

CVE-2026-21637

A flaw in Node.js TLS error handling allows remote attackers to crash or exhaust resources of a TLS server when pskCallback or ALPNCallback are in use. Synchronous exceptions thrown during these callbacks bypass standard TLS error handling paths (tlsClientError and error), causing either immediate process termination or silent file descriptor leaks that eventually lead to denial of service. Because these callbacks process attacker-controlled input during the TLS handshake, a remote client can repeatedly trigger the issue. This vulnerability affects TLS servers using PSK or ALPN callbacks across Node.js versions where these callbacks throw without being safely wrapped.

Maintainer checklist

Verify whether each CVE applies to the NiceOS build.
Compare NVD data with upstream/vendor advisory.
Set final NiceOS status: affected, fixed, not_affected, false_positive, deferred, or not_in_cloud_image.
If affected, decide update/backport strategy according to package policy class.
Run package-class-specific build, upgrade and regression tests.
Add/update niceos_cve_triage entry.
Create NICE-SA advisory if a security update is shipped.
