{"id":"CVE-2026-50200","summary":"Steeltoe's env sanitizer misses connection strings — leaks embedded DB passwords","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, 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.","aliases":["GHSA-q62h-354g-5r85"],"modified":"2026-07-11T03:55:00.279691261Z","published":"2026-06-17T21:44:21.586Z","database_specific":{"cwe_ids":["CWE-200","CWE-319"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50200.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50200.json"},{"type":"ADVISORY","url":"https://github.com/SteeltoeOSS/security-advisories/security/advisories/GHSA-q62h-354g-5r85"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-50200"},{"type":"FIX","url":"https://github.com/SteeltoeOSS/Steeltoe/commit/bef9f14b710232fca3fbe87e48fdd1b9e6b60d43"},{"type":"FIX","url":"https://github.com/SteeltoeOSS/Steeltoe/commit/e50cd31a429b191841120f0d38fa9dda8f751b0a"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/steeltoeoss/steeltoe","events":[{"introduced":"0"},{"fixed":"2d4338d0fc3990a8df90968187d9567004d3fbe7"},{"fixed":"70f147ad094c31ed5d1181592f02b3a2c439a890"},{"fixed":"bef9f14b710232fca3fbe87e48fdd1b9e6b60d43"},{"fixed":"e50cd31a429b191841120f0d38fa9dda8f751b0a"}],"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-2026-50200.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
