A flaw was found in Next.js. A remote unauthenticated attacker could exploit a bypass in a security fix when using middleware.ts with Turbopack. This vulnerability could lead to the disclosure of sensitive information.
Отчет
This Important information disclosure flaw in Next.js allows a remote unauthenticated attacker to bypass a prior security fix when applications utilize middleware.ts with Turbopack. This bypass undermines intended access controls, potentially leading to the exposure of sensitive information in affected Red Hat AMQ and Red Hat Trusted Artifact Signer deployments.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
