html/template may allow JavaScript injection

published 6 months ago
Summary

The Go html/template feature that builds web pages can mishandle certain JavaScript sections, especially when using conditional code or embedded expressions. This can cause the system to fail to properly clean user-supplied data, opening the door for malicious scripts to run in a visitor's browser. Update to the latest version of Go or apply the provided patches to ensure all JavaScript content is correctly escaped.
