CVE-2026-44580 · Next.js: Cross-site scripting in beforeInteractive scripts with untrusted input
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
Next.js is a React framework for building full-stack web applications. From 13.0.0 to before 15.5.16 and 16.2.5, applications that use beforeInteractive scripts together with untrusted content can be vulnerable to cross-site scripting. In affected versions, serialized script content was not escaped safely before being embedded into the document, which could allow attacker-controlled input to break out of the intended script context and execute arbitrary JavaScript in a visitor's browser. This vulnerability is fixed in 15.5.16 and 16.2.5.
