Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-50201 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- Steeltoe.Management.Endpoint (NuGet): affected all versions; fixed in 4.2.0\n- Steeltoe.Management.Endpoint (NuGet): affected all versions; fixed in 4.2.0\n- Steeltoe.Management.EndpointBase (NuGet): affected all versions; fixed in 3.4.0\n- Steeltoe.Management.EndpointBase (NuGet): affected all versions; fixed in 3.4.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-50201/ (Markdown: https://insights.sbomify.com/CVE-2026-50201/index.md)","id":"CVE-2026-50201","markdown":"https://insights.sbomify.com/CVE-2026-50201/index.md","name":"CVE-2026-50201","record":{"aliases":["GHSA-227r-jm2g-7cp4"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Steeltoe management library","requires_auth":"low_privilege","summary":"Low-privilege users can access sensitive heap dumps and environment variables due to insufficient permission checks in Steeltoe actuators.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-285","name":"Improper Authorization"},{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"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()`.","ecosystems":["NuGet"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Steeltoe's sensitive actuators (heapdump/env) only require Restricted permission","id":"CVE-2026-50201","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"NuGet","product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":4,"n_references":3,"next":{"headline":"Steeltoe's static JWKS cache shared across schemes and never invalidated","id":"CVE-2026-50202"},"packages":[{"ecosystem":"NuGet","fixed":["4.2.0"],"introduced":["0"],"last_affected":[],"package":"Steeltoe.Management.Endpoint","purl":null,"source":"GHSA-227r-jm2g-7cp4"},{"ecosystem":"NuGet","fixed":["4.2.0"],"introduced":["0"],"last_affected":[],"package":"Steeltoe.Management.Endpoint","purl":"pkg:nuget/Steeltoe.Management.Endpoint","source":"GHSA-227r-jm2g-7cp4"},{"ecosystem":"NuGet","fixed":["3.4.0"],"introduced":["0"],"last_affected":[],"package":"Steeltoe.Management.EndpointBase","purl":null,"source":"GHSA-227r-jm2g-7cp4"},{"ecosystem":"NuGet","fixed":["3.4.0"],"introduced":["0"],"last_affected":[],"package":"Steeltoe.Management.EndpointBase","purl":"pkg:nuget/Steeltoe.Management.EndpointBase","source":"GHSA-227r-jm2g-7cp4"}],"prev":{"headline":"Steeltoe's env sanitizer misses connection strings — leaks embedded DB passwords","id":"CVE-2026-50200"},"products":["Steeltoe.Management.Endpoint","Steeltoe.Management.EndpointBase"],"published":"2026-06-17","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-18","vendors":["SteeltoeOSS"]},"summary":"Low-privilege users can access sensitive heap dumps and environment variables due to insufficient permission checks in Steeltoe actuators.","url":"https://insights.sbomify.com/CVE-2026-50201/"}
