Vulnerability details
The vulnerability allows a remote user to disclose sensitive information from the host filesystem to the guest.
The vulnerability exists due to improper access control in update_config_by_annotation in src/libs/kata-types/src/annotations/mod.rs when processing untrusted pod annotations. A remote user can set the io.katacontainers.config.runtime.sandbox_bind_mounts annotation to disclose sensitive information from the host filesystem to the guest.
The exposed host paths are bind-mounted read-only into the guest-shared filesystem. This affects runtime-rs only; the Go runtime does not honor the sandbox_bind_mounts annotation.
Affected software
