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.","publishedAt":"2026-09-30T11:30:38.308Z","updatedAt":"2026-09-30T14:28:45.094Z","severity":{"score":2,"label":"Low","version":"4.0","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","source":"Anthropic"},"assigner":"Anthropic","products":["Anthropic @anthropic-ai/claude-code"],"affected":[{"vendor":"Anthropic","product":"@anthropic-ai/claude-code","versions":[{"version":"2.0.68","status":"affected","lessThan":"2.1.260","versionType":"semver"}]}],"references":["https://github.com/anthropics/claude-code/security/advisories/GHSA-gfvf-j8jh-jxxw"],"weaknesses":["CWE-696"],"ingestedAt":"2026-10-29T20:10:23.711Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/103xxx/CVE-2026-103012.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-103012","state":"PUBLISHED","datePublished":"2026-09-30T11:30:38.308Z","dateUpdated":"2026-09-30T14:28:45.094Z","assignerShortName":"Anthropic","assignerOrgId":"98a01053-8a31-4f6d-9aa9-252be161adc6","dateReserved":"2026-09-29T21:06:44.918Z"},"containers":{"cna":{"descriptions":[{"lang":"en","value":"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.
