Istio 1.11.0, 1.10.3 and below, and 1.9.7 and below contain a remotely exploitable vulnerability where an HTTP request with `#fragment` in the path may bypass Istio\u00e2\u20ac\u2122s URI path based authorization policies. Patches are available in Istio 1.11.1, Istio 1.10.4 and Istio 1.9.8. As a work around a Lua filter may be written to normalize the path."

Istio versiones 1.11.0, 1.10.3 y por debajo, y versiones 1.9.7 y por debajo, contienen una vulnerabilidad explotable de forma remota en la que una petici\u00f3n HTTP con el par\u00e1metro \"#fragment\" en la ruta puede omitir las pol\u00edticas de autorizaci\u00f3n basadas en la ruta URI de Istio. Los parches est\u00e1n disponibles en Istio versi\u00f3n 1.11.1, Istio versi\u00f3n 1.10.4 e Istio versi\u00f3n 1.9.8. Como soluci\u00f3n, puede escribirse un filtro Lua para normalizar la ruta."
