Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Ironic Python Agent (ironic-python-agent) versions 1.0.0 through 11.5.0 are affected. In some cases the agent runs grub-install inside a chroot of the deployed partition image, so an attacker who supplies a malicious image can execute code. Upgrade to version 11.6.0 or later.
