{"id":"CVE-2026-103012","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-103012","generatedAt":"2026-10-28T06:34:56.529Z","title":"Claude Code selected an API key stored by Claude Code, for example from an earlier `/login` or written directly to its configuration, ahead of the user's valid Claude Enterprise or Team sign-in when fetching the organization's server-managed settings,…","description":"Claude Code selected an API key stored by Claude Code, for example from an earlier `/login` or written directly to its configuration, ahead of the user's valid Claude Enterprise or Team sign-in when fetching the organization's server-managed settings, even though the session itself authenticated with the Enterprise or Team account. When the settings endpoint rejected that stored key, the session started without the organization's server-managed policy (such as permission deny rules, model restrictions and managed-only locks) or, if a previously cached copy existed on the machine, kept applying that stale copy without receiving later policy changes — while continuing to operate as the organization's account. Triggering this required local access to a device with such a stored API key; the no-policy case additionally required that no managed settings had previously been cached. Endpoint-managed (MDM or file-based) settings were not affected. Claude for Enterprise organizations were affected from version 2.0.68; Claude for Work (Team) organizations from version 2.1.38, when server-managed settings became available to them.\n\nUsers on standard Claude Code auto-update have received this fix already. Users performing manual updates are advised to update to version 2.1.260 or later.\n\nThank you to Tamas Voros / NVIDIA AI Red Team for reporting this issue.","published":"2026-09-30T12:17:12.000Z","lastModified":"2026-09-30T16:12:10.000Z","status":"Awaiting Analysis","sourceIdentifier":"98a01053-8a31-4f6d-9aa9-252be161adc6","cvss":{"version":"4.0","score":2,"severity":"LOW","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-696"],"affected":[],"epss":{"score":0.00105,"percentile":0.01035,"date":"2026-10-27","history":[{"date":"2026-10-01","score":0.00149,"percentile":0.03493}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.10%).
