CVE-2024-11079
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA flaw was found in Ansible-Core. This vulnerability allows attackers to bypass unsafe content protections using the hostvars object to reference and execute templated content. This issue can lead to arbitrary code execution if remote data or module outputs are improperly templated within playbooks.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAnsible-Core contains a vulnerability where the hostvars object can be leveraged to bypass unsafe content protections. Attackers can reference and execute templated content through hostvars, leading to arbitrary code execution when playbooks improperly template remote data or module outputs.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed ansible-core versionRun command: ansible-core --version or pip show ansible-coreAffected if The installed version falls within the vulnerable range before the patch was applied
-
Check for hostvars usage in playbooksSearch playbook files for 'hostvars' references, especially in templated expressions like {{ hostvars[...] }}Affected if Playbooks reference hostvars with dynamically constructed keys or remote data without unsafe wrappers
-
Inspect variable sources for unsafe contentReview inventory, facts, module return values, and registered variables to identify if remote or external data flows into template expressionsAffected if Remote data or module outputs are directly templated without using the | unsafe filter or wrap_async option
-
Verify unsafe protection mechanismsSearch for use of | unsafe filter, unsafe proxy objects, or ANSIBLE_BECOME_ASK_PASS type protections in templating contextsAffected if Unsafe content protections are not applied to hostvars-referenced templated expressions that contain remote data
-
Audit Jinja2 template expressionsReview template expressions in playbooks, especially those using hostvars['inventory_hostname'] or similar constructs, for direct variable interpolationAffected if Playbooks contain template expressions that can resolve to arbitrary content through hostvars manipulation
A user is affected if ansible-core is at a vulnerable version AND playbooks use hostvars to template remote data or module outputs without unsafe content protections.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate Ansible-Core to the patched version and review playbooks to ensure remote data and module outputs are not improperly templated without unsafe wrappers.
