### Invoking incorrect handling of namespaced elements in foreign content in golang.org/x/net/html
[CVE-2026-42506](https://nvd.nist.gov/vuln/detail/CVE-2026-42506) / [GO-2026-5025](https://pkg.go.dev/vuln/GO-2026-5025)

<details>
<summary>More information</summary>

#### 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.

### Invoking failure to reject ASCII-only Punycode-encoded labels in golang.org/x/net/idna
[CVE-2026-39821](https://nvd.nist.gov/vuln/detail/CVE-2026-39821) / [GO-2026-5026](https://pkg.go.dev/vuln/GO-2026-5026)

<details>
<summary>More information</summary>

#### 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".
