CVE-2026-16493 (GCVE-0-2026-16493)

Vulnerability from cvelistv5 – Published: 2026-07-21 17:26 – Updated: 2026-09-04 02:01

Title

Ansible-core: argument injection in ansible-galaxy collection install via git clone (incomplete fix for cve-2026-11332)

Summary

A flaw was found in ansible-core. The _extract_collection_from_git() function in ansible-core's concrete_artifact_manager.py constructs git clone commands without a '--' (end-of-options) separator before user-supplied URLs when installing collections from git sources. An attacker who provides a crafted collection source URI containing git argument injection payloads can achieve arbitrary command execution when a user runs 'ansible-galaxy collection install' with the malicious source. This is an incomplete fix for CVE-2026-11332, which hardened the role install path but missed the equivalent collection install code path.

Severity

7.8 (High)

          "value": "The following practices would help for avoiding exposure and mitigate this flaw:\n\n1. Do not install Ansible collections from untrusted or unverified git sources. Only install collections from trusted sources such as Ansible Galaxy (https://galaxy.ansible.com), Red Hat Automation Hub (https://console.redhat.com/ansible/automation-hub), or verified internal repositories using HTTPS URLs.\n\n2. Carefully inspect any requirements.yml files before running \u0027ansible-galaxy collection install -r requirements.yml\u0027. Verify that all collection sources use legitimate HTTPS URLs and do not contain git+ prefixed URIs with suspicious characters (especially values starting with \u0027-\u0027).\n\n3. Ensure your system\u0027s git version is 2.12 or later, which disables the ext:: transport by default. While this does not fully prevent exploitation (the -ccore.sshCommand technique bypasses transport restrictions), it eliminates one of the exploitation vectors.\n\n4. Restrict the GIT_ALLOW_PROTOCOL environment variable to only necessary protocols (e.g. https, ssh) and never include \u0027ext\u0027 unless absolutely required."

Only install collections from trusted sources such as Ansible Galaxy (https://galaxy.ansible.com), Red Hat Automation Hub (https://console.redhat.com/ansible/automation-hub), or verified internal repositories using HTTPS URLs.\n\n2. Carefully inspect any requirements.yml files before running \u0027ansible-galaxy collection install -r requirements.yml\u0027. Verify that all collection sources use legitimate HTTPS URLs and do not contain git+ prefixed URIs with suspicious characters (especially values starting with \u0027-\u0027).\n\n3. Ensure your system\u0027s git version is 2.12 or later, which disables the ext:: transport by default. While this does not fully prevent exploitation (the -ccore.sshCommand technique bypasses transport restrictions), it eliminates one of the exploitation vectors.\n\n4. Restrict the GIT_ALLOW_PROTOCOL environment variable to only necessary protocols (e.g. https, ssh) and never include \u0027ext\u0027 unless absolutely required."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
