Go Net HTML parser is vulnerable to denial of service

CVE-2026-25680 / GHSA-5cv4-jp36-h3mw / GO-2026-5028

More information

Details

In Go Net (golang.org/x/net) before verion 0.55.0, parsing arbitrary HTML can consume excessive CPU time, possibly leading to denial of service.

Severity

  • CVSS Score: 6.5 / 10 (Medium)
  • Vector String: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H

Invoking incorrect handling of namespaced elements in foreign content in golang.org/x/net/html

CVE-2026-42506 / GO-2026-5025

More information

Details

Parsing arbitrary HTML which is then rendered using Render can result in an unexpected HTML tree. This can be leveraged to execute XSS attacks in applications that attempt to sanitize input HTML before rendering.

Severity

Invoking failure to reject ASCII-only Punycode-encoded labels in golang.org/x/net/idna

CVE-2026-39821 / GO-2026-5026

More information

Details

The ToASCII and ToUnicode functions incorrectly accept Punycode-encoded labels that decode to an ASCII-only label. For example, ToUnicode("xn--example-.com") incorrectly returns the name "example.com" rather than an error.

This behavior can lead to privilege escalation in programs using the idna package. For example, a program which performs privilege checks on the ASCII hostname may reject "example.com" but permit "xn--example-.com". If that program subsequently converts the ASCII hostname to Unicode, it will inadvertently permits access to the Unicode name "example.com".
