CVE-2026-12405: Rubygem-foreman_remote_execution: command injection in job invocations via effective_user parameter

Noroxi assessment

Priority: Monitor (action score 35/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 1.5% (FIRST EPSS); higher than 75.7% of all records.
Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
Fixed version: foreman (Red Hat:satellite_capsule:6.16::el8) 0:3.12.0.23-1.el8sat; foreman-debug (Red Hat:satellite_capsule:6.16::el8) 0:3.12.0.23-1.el8sat; foreman-pcp (Red Hat:satellite_capsule:6.16::el8) 0:3.12.0.23-1.el8sat.

Low priority for now. Upgrade to foreman (Red Hat:satellite_capsule:6.16::el8) 0:3.12.0.23-1.el8sat; foreman-debug (Red Hat:satellite_capsule:6.16::el8) 0:3.12.0.23-1.el8sat; foreman-pcp (Red Hat:satellite_capsule:6.16::el8) 0:3.12.0.23-1.el8sat or later.

Primary sources: NVD · CVE.org · FIRST EPSS

A flaw was found in rubygem-foreman_remote_execution. A command injection vulnerability exists in the Red Hat Satellite API (/api/v2/job_invocations). When a job template has the effective_user property marked as overridable: true, the application fails to properly sanitize the effective_user input provided during the API request. The exploitation does not rely on the content or logic of the Job Template/playbook itself; rather, the injection occurs during the instantiation of the job execution environment by the Satellite server. An attacker with permissions to execute job templates can inject arbitrary shell commands into this parameter, which are executed on the target infrastructure with the privileges of the execution user.
