CVE-2026-16493— Ansible-core: argument injection in ansible-galaxy collection install via git clone (incomplete fix for cve-2026-11332)

Quick assessment

Affected

Red Hat Red Hat Satellite 6.17 for RHEL 9

Exploitation

No confirmed in-the-wild exploitation; assess based on exposure

Recommended action

Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

ansible是美国Ansible公司开源的一款IT自动化配置工具。 ansible存在命令注入漏洞，该漏洞源于ansible-core中_extract_collection_from_git()函数在从git源安装集合时，未在用户提供的URL前添加'--'（选项结束）分隔符，导致攻击者可通过特制的集合源URI注入git参数，当用户运行'ansible-galaxy collection install'时实现任意命令执行。

Vulnerability Title

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

Source: CVE Program / CVE List V5

Vulnerability Description

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.
