Vulnerabilidad de limpieza incompleta en Apache Tomcat. Al reciclar varios objetos internos en Apache Tomcat desde 11.0.0-M1 hasta 11.0.0-M11, desde 10.1.0-M1 hasta 10.1.13, desde 9.0.0-M1 hasta 9.0.80 y Desde 8.5.0 hasta 8.5.93, un error podría hacer que Tomcat se salte algunas partes del proceso de reciclaje, lo que provocaría que se filtrara información de la solicitud/respuesta actual a la siguiente. Se recomienda a los usuarios actualizar a la versión 11.0.0-M12 en adelante, 10.1.14 en adelante, 9.0.81 en adelante o 8.5.94 en adelante, lo que soluciona el problema.

A flaw was found in Apache Tomcat. Tomcat may skip, after an error, the recycling of the internal objects that the next request/response process might use, resulting in information leaking from one request to the next. This flaw allows a malicious user to have access to this information.

It was discovered that Tomcat did not include the secure attribute for session cookies when using the RemoteIpFilter with requests from a reverse proxy. An attacker could possibly use this issue to leak sensitive information. This issue was fixed for tomcat8 on Ubuntu 18.04 LTS and for tomcat9 on Ubuntu 24.04 LTS, Ubuntu 24.10, and Ubuntu 25.04. It was discovered that Tomcat incorrectly recycled certain objects, which could lead to information leaking from one request to the next. An attacker could potentially use this issue to leak sensitive information. This issue was fixed for tomcat8 on Ubuntu 18.04 LTS and for tomcat9 on Ubuntu 24.04 LTS, Ubuntu 24.10, and Ubuntu 25.04.
