Kerentanan Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') pada unjs unhead. Skor CVSS 3.1 6.1 (Medium) menurut NVD.

Deskripsi (NVD)

Unhead is a document head and template manager. Prior to 2.1.11, useHeadSafe() can be bypassed to inject arbitrary HTML attributes, including event handlers, into SSR-rendered <head> tags. This is the composable that Nuxt docs recommend for safely handling user-generated content. The acceptDataAttrs function (safe.ts, line 16-20) allows any property key starting with data- through to the final HTML. It only checks the prefix, not whether the key contains spaces or other characters that break HTML attribute parsing. This vulnerability is fixed in 2.1.11.
