{"id":"CVE-2026-50200","state":"PUBLISHED","title":"Steeltoe's env sanitizer misses connection strings — leaks embedded DB passwords","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:<name>` or Steeltoe Connectors' `Steeltoe:Client:<type>: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.","publishedAt":"2026-06-17T21:44:21.586Z","updatedAt":"2026-06-18T15:45:27.834Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["SteeltoeOSS Steeltoe.Management.Endpoint","SteeltoeOSS Steeltoe.Management.EndpointCore"],"affected":[{"vendor":"SteeltoeOSS","product":"Steeltoe.Management.Endpoint","versions":[{"version":"< 4.2.0","status":"affected"}]},{"vendor":"SteeltoeOSS","product":"Steeltoe.Management.EndpointCore","versions":[{"version":"< 3.4.0","status":"affected"}]}],"references":["https://github.com/SteeltoeOSS/security-advisories/security/advisories/GHSA-q62h-354g-5r85","https://github.com/SteeltoeOSS/Steeltoe/commit/bef9f14b710232fca3fbe87e48fdd1b9e6b60d43","https://github.com/SteeltoeOSS/Steeltoe/commit/e50cd31a429b191841120f0d38fa9dda8f751b0a"],"weaknesses":["CWE-200","CWE-319"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/50xxx/CVE-2026-50200.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-50200","state":"PUBLISHED","datePublished":"2026-06-17T21:44:21.586Z","dateUpdated":"2026-06-18T15:45:27.834Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-03T22:05:13.645Z"},"containers":{"cna":{"title":"Steeltoe's env sanitizer misses connection strings — leaks embedded DB passwords","descriptions":[{"lang":"en","value":"Steeltoe is an open source project that provides a collection of libraries that helps users build cloud-native applications.
