CVE-2026-75777

Local container escape via unrestricted system calls

Published Sep 10, 2026 · Updated Sep 10, 2026

Container isolation failure in IBM Aspera Enterprise WebApps 1.0.0 through 1.0.5 allows local users to escape to the host. The deployed container permits unrestricted system calls instead of enforcing a syscall restriction profile, leaving host-impacting kernel interfaces reachable from inside the workload. Exploitation requires low-privileged access inside an affected application container; a successful escape crosses the container boundary and grants access to the underlying host.
