CVE-2025-22872
MEDIUM6.5EPSS 0.02%Incorrect Neutralization of Input During Web Page Generation in x/net in golang.org/x/net
Published: 4/16/2025Modified: 4/28/2026
Description
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. <math>, <svg>, etc contexts).
