Description

When running Apache Tomcat 7.0.0 to 7.0.79 on Windows with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default to false) it was possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.

CVE-2026-65960
Tetragon is an eBPF-based security observability and runtime enforcement project. Versions before 1.7.0 can use a Helm default that exposes the privileged Tetragon gRPC API through an unauthenticated TCP listener on localhost:54321. An attacker who can run or compromise same-node hostNetwork pods can reach the listener and invoke privileged methods without authentication. These methods can add, delete, or reconfigure tracing policies and change debug settings, potentially resulting in privilege escalation or container escape. Version 1.7.0 changes the default endpoint to a Unix-domain socket. Deployments that do not expose an unauthenticated TCP listener are not affected.
