An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-50200 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.EndpointCore (NuGet): affected all versions; fixed in 3.4.0\n- Steeltoe.Management.EndpointCore (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-2026-50200/ (Markdown: https://insights.sbomify.com/CVE-2026-50200/index.md)","id":"CVE-2026-50200","markdown":"https://insights.sbomify.com/CVE-2026-50200/index.md","name":"CVE-2026-50200","record":{"aliases":["GHSA-q62h-354g-5r85"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Steeltoe management library","requires_auth":"none","summary":"Attackers can read database passwords from environment endpoints because the sanitizer fails to redact connection strings.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-319","name":"Cleartext Transmission of Sensitive Information"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"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, the `Sanitizer` component in the Environment actuator redacts configuration values by matching the configuration key name against a suffix list. The default list (`password`, `secret`, `key`, `token`, `.*credentials.*`, `vcap_services`) does not cover the standard .NET pattern `ConnectionStrings:\u003cname\u003e` or Steeltoe Connectors' `Steeltoe:Client:\u003ctype\u003e:Default:ConnectionString`. There is no value-based scrubbing, so full connection string values including embedded `Password=` and `user:pass@host` segments are returned verbatim in `/actuator/env` responses. Steeltoe.Management.Endpoint 4.2.0 and Steeltoe.Management.EndpointCore 3.4.0 patch the issue. If an immediate upgrade is not possible: On the standard path, remove `env` from the actuator exposure list; add `.*connectionstring.*` to `KeysToSanitize` as a defense-in-depth measure for both paths; and/or require authorization on actuator endpoints.","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 env sanitizer misses connection strings — leaks embedded DB passwords","id":"CVE-2026-50200","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"NuGet","product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":4,"n_references":3,"next":{"headline":"Steeltoe's sensitive actuators (heapdump/env) only require Restricted permission","id":"CVE-2026-50201"},"packages":[{"ecosystem":"NuGet","fixed":["4.2.0"],"introduced":["0"],"last_affected":[],"package":"Steeltoe.Management.Endpoint","purl":null,"source":"GHSA-q62h-354g-5r85"},{"ecosystem":"NuGet","fixed":["4.2.0"],"introduced":["0"],"last_affected":[],"package":"Steeltoe.Management.Endpoint","purl":"pkg:nuget/Steeltoe.Management.Endpoint","source":"GHSA-q62h-354g-5r85"},{"ecosystem":"NuGet","fixed":["3.4.0"],"introduced":["0"],"last_affected":[],"package":"Steeltoe.Management.EndpointCore","purl":null,"source":"GHSA-q62h-354g-5r85"},{"ecosystem":"NuGet","fixed":["3.4.0"],"introduced":["0"],"last_affected":[],"package":"Steeltoe.Management.EndpointCore","purl":"pkg:nuget/Steeltoe.Management.EndpointCore","source":"GHSA-q62h-354g-5r85"}],"prev":{"headline":"Wallos: Cross-user Fixer/API Layer credential consumption in exchange-rate refresh","id":"CVE-2026-50199"},"products":["Steeltoe.Management.Endpoint","Steeltoe.Management.EndpointCore"],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-18","vendors":["SteeltoeOSS"]},"summary":"Attackers can read database passwords from environment endpoints because the sanitizer fails to redact connection strings.","url":"https://insights.sbomify.com/CVE-2026-50200/"}
