CVE-2026-42552
Full vulnerability record from the local CVENow database.
Description
Flight is an extensible micro-framework for PHP. Prior to 3.18.1, the default error handler Engine::_error() writes the full exception message, exception code, and stack trace (including absolute filesystem paths) directly into the HTTP 500 response, with no debug gating. Production deployments leak internal paths, any secret interpolated into an exception message, and full module structure — giving attackers primitives for chaining other weaknesses (LFI, path traversal). This vulnerability is fixed in 3.18.1.

"value": "Flight es un micro-framework extensible para PHP. Antes de la versión 3.18.1, el gestor de errores predeterminado Engine::_error() escribe el mensaje completo de la excepción, el código de la excepción y el seguimiento de la pila (incluyendo rutas absolutas del sistema de archivos) directamente en la respuesta HTTP 500, sin control de depuración. Las implementaciones en producción filtran rutas internas, cualquier secreto interpolado en un mensaje de excepción y la estructura completa del módulo - proporcionando a los atacantes primitivas para encadenar otras debilidades (LFI, salto de ruta). Esta vulnerabilidad está corregida en la versión 3.18.1."
