CVE-2026-72925: SWC HTML minifier may allow script element breakout when minifying embedded JSON

@swc/html minifies JSON contained in script elements such as application/json and application/ld+json by parsing and serializing the JSON value.

Before the patched versions, JSON serialization could convert escaped less-than signs such as \u003C into literal < characters. If the JSON contained an escaped </script> sequence, the generated HTML could terminate the containing script element early because HTML tokenization occurs before the JSON is consumed.

Applications that minify HTML containing attacker-controlled JSON data could therefore transform inert data into active markup. A crafted payload could execute script in the origin of the generated page.
