GO-2026-6599

Reset context tracking on consecutive template expressions in html/template

Quick fix

GO-2026-6599 — stdlib: upgrade to the fixed version with the command below.

go get stdlib@v1.26.9

Details

When a JavaScript template literal contains consecutive expressions, the context tracking state was not properly reset upon entering a new expression.

We now ensure that template-literal expression entries correctly reset context variables so all subsequent regular expression literals are accurately recognized and escaped.
