Description

This security bulletin contains information about 1 vulnerability.


1) Improper error handling (CVE-ID: CVE-2026-21710)

CWE-ID: CWE-388 - Error Handling

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to improper handling of special property names in HTTP headers in req.headersDistinct when parsing incoming HTTP requests. A remote attacker can send a request with a header named __proto__ to trigger a TypeError when the application accesses req.headersDistinct, crashing the Node.js process.

The exception occurs synchronously in a property getter and cannot be caught without wrapping every access in try/catch.
