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()`.","publishedAt":"2026-06-17T21:46:18.114Z","updatedAt":"2026-06-18T12:51:12.653Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["SteeltoeOSS Steeltoe.Management.Endpoint","SteeltoeOSS Steeltoe.Management.EndpointBase"],"affected":[{"vendor":"SteeltoeOSS","product":"Steeltoe.Management.Endpoint","versions":[{"version":"< 4.2.0","status":"affected"}]},{"vendor":"SteeltoeOSS","product":"Steeltoe.Management.EndpointBase","versions":[{"version":"< 3.4.0","status":"affected"}]}],"references":["https://github.com/SteeltoeOSS/security-advisories/security/advisories/GHSA-227r-jm2g-7cp4","https://github.com/SteeltoeOSS/Steeltoe/commit/b39defa4db5f44f8696c456866b3a5b900d8d96b","https://github.com/SteeltoeOSS/Steeltoe/commit/da6c604decd992f61aeef763f5814102dcb088c7"],"weaknesses":["CWE-269","CWE-285"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/50xxx/CVE-2026-50201.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-50201","state":"PUBLISHED","datePublished":"2026-06-17T21:46:18.114Z","dateUpdated":"2026-06-18T12:51:12.653Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-03T22:05:13.645Z"},"containers":{"cna":{"title":"Steeltoe's sensitive actuators (heapdump/env) only require Restricted permission","descriptions":[{"lang":"en","value":"Steeltoe is an open source project that provides a collection of libraries that helps users build cloud-native applications.
