{"id":"UBUNTU-CVE-2026-84503","details":"A flaw was found in ansible-core's ansible.builtin.git module. 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.","modified":"2026-11-11T09:41:12.010704006Z","published":"2026-11-10T00:00:00Z","upstream":["CVE-2026-84503"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-84503"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-84503"},{"type":"REPORT","url":"access.redhat.com/downloads/content/package-browser"}],"affected":[{"package":{"name":"ansible-core","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/ansible-core?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.12.0-1","2.12.0-1ubuntu0.1"],"ecosystem_specific":{"binaries":[{"binary_name":"ansible-core","binary_version":"2.12.0-1ubuntu0.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-84503.json"}},{"package":{"name":"ansible-core","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/ansible-core?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.14.9-2","2.14.11-1","2.14.11-2","2.14.13-1","2.16.3-0ubuntu1","2.16.3-0ubuntu2"],"ecosystem_specific":{"binaries":[{"binary_version":"2.16.3-0ubuntu2","binary_name":"ansible-core"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-84503.json"}},{"package":{"name":"ansible-core","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/ansible-core?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.20.1-1","2.21.1~rc1-1","2.21.1~rc1-2","2.21.1~rc1-2ubuntu1","2.22.0~beta2-1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.22.0~beta2-1","binary_name":"ansible-core"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-84503.json"}},{"package":{"name":"ansible-core","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/ansible-core?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.19.0-1ubuntu1","2.19.4-1","2.20.1-1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.20.1-1","binary_name":"ansible-core"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-84503.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
