Medium Risk
This Affects:
spatie/schema-orgTL;DR
Improper neutralization of user-controlled data in toScript() output in spatie/schema-org allowed HTML script-tag breakout when attacker-supplied values were embedded in JSON-LD metadata. Because <script type="application/ld+json"> blocks were generated without escaping HTML tag delimiters, crafted input containing </script> sequences could inject executable JavaScript into the page. Successful exploitation could result in stored or reflected cross-site scripting.
