CVE-2026-44373

Nitro is a next generation server toolkit. Prior to 3.0.260429-beta, an attacker could bypass a proxy route rule by sending percent-encoded path traversal (..%2f) in the URL, causing Nitro to forward a request that the upstream resolved outside the configured scope. This vulnerability is fixed in 3.0.260429-beta.

Summary		(es) Nitro es un kit de herramientas de servidor de próxima generación. Antes de 3.0.260429-beta, un atacante podría eludir una regla de ruta de proxy enviando un salto de ruta codificado por porcentaje (..%2f) en la URL, haciendo que Nitro reenviara una solicitud que el upstream resolvió fuera del alcance configurado. Esta vulnerabilidad está corregida en 3.0.260429-beta.
