{"id":"CVE-2026-50201","summary":"Steeltoe's sensitive actuators (heapdump/env) only require Restricted permission","details":"Steeltoe is an open source project that provides a collection of libraries that helps users build cloud-native applications. In Steeltoe.Management.Endpoint prior to version 4.2.0 and Steeltoe.Management.EndpointCore prior to version 3.4.0, all Steeltoe actuator endpoints default to `EndpointPermissions.Restricted`, which is mappeds to Cloud Foundry's `read_basic_data` permission (granted to Space Auditors and similar low-trust roles). Sensitive actuators including heap dump, environment, and thread dump do not raise this to `EndpointPermissions.Full`, so CF's `read_sensitive_data` permission flag is not enforced for those endpoints. Spring Boot's equivalent Cloud Foundry integration gates these endpoints with `read_sensitive_data` by default. Steeltoe.Management.Endpoint 4.2.0 and Steeltoe.Management.EndpointCore 3.4.0 patch the issue. If an immediate upgrade is not possible, explicitly set `RequiredPermissions = EndpointPermissions.Full` in the options for `HeapDumpEndpointOptions`, `EnvironmentEndpointOptions`, and `ThreadDumpEndpointOptions`; and/or if heap dump, thread dump, or environment are not needed in production, register only the required actuators individually instead of using `AddAllActuators()`.","aliases":["GHSA-227r-jm2g-7cp4"],"modified":"2026-07-11T03:53:29.664021085Z","published":"2026-06-17T21:46:18.114Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-269","CWE-285"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50201.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50201.json"},{"type":"ADVISORY","url":"https://github.com/SteeltoeOSS/security-advisories/security/advisories/GHSA-227r-jm2g-7cp4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-50201"},{"type":"FIX","url":"https://github.com/SteeltoeOSS/Steeltoe/commit/b39defa4db5f44f8696c456866b3a5b900d8d96b"},{"type":"FIX","url":"https://github.com/SteeltoeOSS/Steeltoe/commit/da6c604decd992f61aeef763f5814102dcb088c7"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/steeltoeoss/steeltoe","events":[{"introduced":"0"},{"fixed":"2d4338d0fc3990a8df90968187d9567004d3fbe7"},{"fixed":"70f147ad094c31ed5d1181592f02b3a2c439a890"},{"fixed":"b39defa4db5f44f8696c456866b3a5b900d8d96b"},{"fixed":"da6c604decd992f61aeef763f5814102dcb088c7"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"4.2.0"},{"fixed":"3.4.0"}]}}],"versions":["4.1.0","4.0.0","3.3.0","4.0.0-rc1","3.2.8","4.0.0-beta1","3.2.7","3.2.6","3.2.5","3.2.4","3.2.3","3.2.2","3.2.1","3.2.0","3.2.0-rc1","3.1.1","3.1.0","3.1.0-rc2","3.1.0-rc1","3.0.x_2021-Jan-12","3.0.2","3.0.1","3.0.0","3.0.0-rc1","3.0.0-m3","3.0.0-m2","3.0.0-m1"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-50201.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
