HTTP Proxy bypass using IPv6 Zone IDs in golang.org/x/net

CVE-2025-22870 / GHSA-qxp5-gwg8-xv66

More information

Details

Matching of hosts against proxy patterns can improperly treat an IPv6 zone ID as a hostname component. For example, when the NO_PROXY environment variable is set to "*.example.com", a request to "[::1%25.example.com]:80` will incorrectly match and not be proxied.

golang.org/x/net vulnerable to Cross-site Scripting

CVE-2025-22872 / GHSA-vvgc-356p-c3xw

More information

Details

The tokenizer incorrectly interprets tags with unquoted attribute values that end with a solidus character (/) as self-closing. When directly using Tokenizer, this can result in such tags incorrectly being marked as self-closing, and when using the Parse functions, this can result in content following such tags as being placed in the wrong scope during DOM construction, but only when tags are in foreign content (e.g. , , etc contexts).

Non-linear parsing of case-insensitive content in golang.org/x/net/html

CVE-2024-45338 / GHSA-w32m-9786-jp63 / GO-2024-3333

More information

Details

An attacker can craft an input to the Parse functions that would be processed non-linearly with respect to its length, resulting in extremely slow parsing. This could cause a denial of service.

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".
