Summary

Duplicate Advisory: Cross-site scripting via <NoScript> slot content in Nuxt's head components

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-m3q2-p4fw-w38m. This link is maintained to preserve external references.

Original 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.

Severity

2.3 (Low)
