{"schema":"threatline.record/2","record":{"id":"CVE-2026-100611","aliases":["GHSA-2x4j-p4pr-fvp8"],"summary":"Capgo apikey_manager Role Privilege Escalation via Incomplete Role Deny-list","details":"Capgo (capgo.app backend, versions ≤ 12.261.0) improperly restricts which roles the apikey_manager organization role may bind to newly created API keys. When an authenticated user holding only apikey_manager (permissions org.manage_apikeys and org.read) calls POST /apikey with a JWT session, the only checks applied are the org.manage_apikeys permission, a fixed deny-list of assignable role names (APIKEY_MANAGER_DENIED_ASSIGNABLE_ROLES in public/apikey/scope.ts), and a priority-rank comparison in createRoleBindingForPrincipal (private/role_bindings.ts). No check verifies that the caller actually holds the permissions conferred by the role being assigned. Because the deny-list omits the deploy roles app_developer, app_uploader, channel_developer and channel_uploader, and apikey_manager is seeded with priority_rank 78 — higher than those roles' ranks (68, 66, 58, 57) — the rank check also passes. As a result, an apikey_manager who cannot upload bundles or promote channels can mint an API key bound to a deploy role and use it to push arbitrary OTA JavaScript updates to all end users of the organization's apps. As of the advisory publication no patched version was available.","categories":["Unclassified"],"product":"capgo.app","vendor":"Cap-go","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100611","source_modified_at":"2026-09-30T17:20:05.706Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"capgo.app","vendor":"Cap-go","versions":[{"version":"0","status":"affected","versionType":"semver","lessThanOrEqual":"12.261.0"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":7.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00221,"percentile":0.11953,"score_date":"2026-10-23"},"published_at":"2026-09-26T13:22:53.315Z","modified_at":"2026-09-30T17:20:05.706Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-100611","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-30T17:20:05.706Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-100611","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/Cap-go/capgo.app/security/advisories/GHSA-2x4j-p4pr-fvp8","tags":["exploit"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/capgo-apikey-manager-role-privilege-escalation-via-incomplete-role-deny-list","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-28T17:09:10.962717Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-30T17:20:05.706Z","content_hash":"7a1e90e2a6dfb3f73c4afdaf2ce07946e72e89da1b15ca9fc3a58ab2dd98f8af"}}
