CVE-2026-15743

Catalyst::Plugin::Static::Simple versions through 0.38 for Perl mark responses as publicly cacheable. The _serve_static method always sets the Cache-Control header to "public", with no means of overriding it. This advises proxies that the content may be stored in a shared cache, and may be reused in responses to requests from other users. (This includes requests with an Authorization header.) Configuring the expires time to "0" to disable caching, as documented, is ignored.

Summary		(es) Las versiones de Catalyst::Plugin::Static::Simple hasta la 0.38 para Perl marcan las respuestas como públicamente cacheables. El método _serve_static siempre establece el encabezado Cache-Control en ’public’, sin ningún medio para anularlo. Esto advierte a los proxies que el contenido puede almacenarse en una caché compartida y puede reutilizarse en respuestas a solicitudes de otros usuarios. (Esto incluye solicitudes con un encabezado de autorización.) Configurar el tiempo de caducidad (expires) en ’0’ para deshabilitar el almacenamiento en caché, como se documenta, es ignorado.
