Description

Nuxt before 4.4.7 (and the 3.x branch before 3.21.7) contains a cross-site scripting vulnerability in the NoScript component that writes slot content to innerHTML without escaping. Attackers can inject malicious scripts through untrusted data in NoScript slots, such as route.query parameters, which execute in the document context when the noscript tag is implicitly closed by script tags.
