A flaw was found in Next.js. This vulnerability allows an attacker to bypass security checks in web applications that use Next.js middleware to protect specific web pages. By sending specially crafted web addresses, an attacker can access protected content without proper authorization. This could lead to unauthorized viewing of sensitive information or access to restricted features. Next.js: Next.js: Authorization bypass via crafted query parameters This is an Important authorization bypass flaw in Next.js applications, which are utilized in Red Hat AMQ, Red Hat Trusted Artifact Signer, and Red Hat Enterprise Linux AI. The vulnerability arises when applications use Next.js middleware to protect dynamic routes, allowing attackers to access restricted content by manipulating query parameters. This bypass occurs because specially crafted parameters can alter the route value seen by the page while the visible path remains unchanged, circumventing intended security controls. The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.
