On systems where /proc is mounted without process-hiding mitigations (such as hidepid), which is the default in WSL, an unprivileged local user or process in the same WSL instance can read the token from /proc/<pid>/cmdline while the attach process is running. The leaked token could then be used to attach other machines to the victim's Ubuntu Pro subscription and gain unauthorized access to Ubuntu Pro services.","state":0,"publishedAt":"2026-09-29T14:11:19.35+00:00","modifiedAt":"2026-09-30T15:28:19.783+00:00","affected":[{"ecosystem":"Vendor product","name":"wsl-pro-service","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Canonical\",\n                    \"product\": \"Ubuntu Pro for WSL\",\n                    \"platforms\": [\n                        \"Linux\"\n                    ],\n                    \"packageName\": \"wsl-pro-service\",\n                    \"repo\": \"https://github.com/canonical/ubuntu-pro-for-wsl\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0.1.1\",\n                            \"lessThan\": \"0.1.19ubuntu2\",\n                            \"versionType\": \"ubuntu-resolute\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0.1.1\",\n                            \"lessThan\": \"0.1.18~24.04.3\",\n                            \"versionType\": \"ubuntu-noble\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0.1.1\",\n                            \"lessThan\": \"0.1.18~22.04.2\",\n                            \"versionType\": \"ubuntu-jammy\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0.1.1\",\n                            \"lessThan\": \"0.1.18~20.04.2\",\n                            \"versionType\": \"ubuntu-focal\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":5.7,"severity":"MEDIUM"}],"references":["https://github.com/canonical/ubuntu-pro-for-wsl/pull/1816","https://github.com/canonical/ubuntu-pro-for-wsl/commit/11c164a37b806bcf2a2304beb0d65e406739778b","https://ubuntu.com/security/CVE-2026-102371"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-102371","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-102371","identifiers":["CVE-2026-102371"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
