From 0.2.0 until 7.1.2, the @astrojs/solid-js renderer inserted a named slot into the quoted name attribute of an astro-slot wrapper without HTML escaping. A request-controlled slot name containing a quote could terminate the attribute and inject active HTML. Exploitation required a hydrated Solid component using a client:* directive and dynamic access to the attacker-chosen slot property; a component that did not render that slot emitted only escaped fallback content. This issue is fixed in version 7.1.2."
