## Description:

This update for nodejs20 fixes the following issues:

Update to version 20.20.2.

  * CVE-2026-21717: trivially predictable hash collisions due to flaw in V8's
    string hashing mechanism allows for performance degradation via a crafted
    request (bsc#1260494).
  * CVE-2026-21716: incomplete fix for CVE-2024-36137 allows promise-based
    FileHandle methods to be used to modify file permissions and ownership on
    already-open file descriptors (bsc#1260462).
  * CVE-2026-21715: flaw in the Permission Model filesystem enforcement allows
    for file existence disclosure and filesystem path enumeration via
    `fs.realpathSync.native()` (bsc#1260482).
  * CVE-2026-21714: memory leak in Node.js HTTP/2 server allows for resource
    exhaustion via `WINDOW_UPDATE` frames sent on stream 0 (bsc#1260480).
  * CVE-2026-21713: timing side-channel due to flaw in Node.js HMAC verification
    allows for discovery of HMAC values and potential MAC forgery (bsc#1260463).
  * CVE-2026-21710: uncaught `TypeError` when handling HTTP requests allows for
    a process crash via requests with a header named `__proto__` when the
    application accesses `req.headersDistinct` (bsc#1260455).
  * CVE-2026-21637: flaw in TLS error handling allows for resource exhaustion
    and crash when `pskCallback` or `ALPNCallback` are in use (bsc#1256576).
