This vulnerability affects PyPI packages β€” download data is not available via public APIs for these ecosystems. ## Description An issue was discovered in OpenStack ironic-python-agent 1.0.0 through 11.5.0. Ironic Python Agent (IPA) sometimes executes grub-install from within a chroot of the deployed partition image, leading to code execution in the case of a malicious image. ## Affected Packages 1 total 1 fixed Ecosystem Package Vulnerable range Fix 🐍PyPI `ironic-python-agent` β‰₯ 1.0.0&&< 11.6.0 11.6.0`pip install --upgrade 'ironic-python-agent==11.6.0'` ## Affected Products 1 product Β· 1 configurations Application `ironic python agent`openstack β‰₯ 1.0.0 && ≀ 11.5.0 range ## Detection & mitigation playbook Open-source dependency 1. ### Detect Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ironic-python-agent, including transitive dependencies β€” a direct dependency you never call can still pull in a vulnerable version. 2. ### Fix Update ironic-python-agent to 11.6.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range β€” O3 confirms CVE-2026-43003 is resolved across your whole dependency graph. 3. ### Workarounds Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does. ## Fixing This On Your OS If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below β€” it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project. Red HatImportant Workaround published by Red Hat > Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
