Red Hat Subscription Management (RHSM) authentication tokens are passed as command-line arguments to background helper processes during image retrieval operations. A local, unprivileged attacker on a system permitting cross-user process inspection can view these arguments while the process is active. This flaw can lead to information disclosure, potentially allowing unauthorized access to RHSM resources within the token's validity period.\n\n## Affected\n\n- `cockpit-machines (all versions)`\n- `cockpit-machines (all versions)`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n### Workarounds\n\nMitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 9 · no fix planned: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 9 · updated 2026-10-20 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-113495.json)","depth":"sunlit","depthScore":28,"depthScoreParts":{"impact":27.5,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
