CVE-2026-93981

A flaw was found in hono/jsx. This vulnerability occurs because the software fails to properly escape plain strings when they are rendered in certain contexts during server-side rendering. A remote attacker can exploit this by providing specially crafted input, leading to Cross-Site Scripting (XSS). This allows the attacker to inject malicious code into web pages viewed by other users, potentially compromising user sessions or defacing the website.
