CVE-2026-10037

CVE-2026-10037 · Sandbox Escape in Ubuntu OpenJDK Packages via xdg-desktop-portal

This page contains facts from public vulnerability sources. Check the original advisory before updating.

A sandbox escape vulnerability exists in the OpenJDK packages provided in Ubuntu. The .jar MIME handlers installed by these packages execute files marked as executable when the mailcap package is installed. A compromised or malicious sandboxed application with access to the OpenURI portal via xdg-desktop-portal-gtk can write a malicious .jar file to the host file system, set its executable bit, and trigger the handler to execute arbitrary code outside of the sandbox environment.
