The masking only covers the `UserInfo` portion of the URI (inline `user:password@host` credentials) and does not inspect the query string. With `IncludeQueryString` enabled by default, any secrets carried in query strings (for example: OAuth tokens, password-reset tokens, signed-URL signatures, API keys) are returned verbatim in the `uri` field of the response and written to logs at DEBUG level.\n\n## Impact\n\nAny caller who can reach `/actuator/httpexchanges` can receive full request URIs from prior traffic, including any secrets those URIs contained in their query strings. Applications with DEBUG-level logging enabled for the `Steeltoe.Management.Endpoint.Actuators.HttpExchanges` namespace also write these URIs to their application logs.\n\n## Affected configuration\n\n- `httpexchanges` is explicitly added to the actuator exposure list (`Management:Endpoints:Web:Exposure:Include`). It is not included by default.\n- The application handles requests that carry secrets in query strings, such as OAuth callbacks, signed URLs, or password-reset links.\n- DEBUG logging is enabled for `Steeltoe.Management.Endpoint.Actuators.HttpExchanges` (log exposure only).\n\n## Mitigations\n\nIf an immediate upgrade is not possible:\n\n- Remove `httpexchanges` from the actuator exposure list, or restrict it behind authentication.\n- Set `Management:Endpoints:HttpExchanges:IncludeQueryString` to `false` to strip query strings from recorded exchanges entirely.","state":0,"publishedAt":"2026-09-17T18:01:30+00:00","modifiedAt":"2026-09-17T18:15:04.1692678+00:00","affected":[{"ecosystem":"NuGet","name":"Steeltoe.Management.Endpoint","ranges":[{"type":"ECOSYSTEM","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"4.3.0"}]}],"versions":["1.1.0","1.1.0-rc3","4.0.0","4.0.0-beta1","4.0.0-rc1","4.1.0","4.2.0"],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/SteeltoeOSS/security-advisories/security/advisories/GHSA-8phw-xrj9-cpqp","https://github.com/SteeltoeOSS/Steeltoe/commit/9bf0ecb9f2d4a34b65f61d41c5625d49071ae9fa","https://github.com/SteeltoeOSS/Steeltoe/releases/tag/4.3.0","https://github.com/SteeltoeOSS/security-advisories"],"sourceUrl":"https://github.com/advisories/GHSA-8phw-xrj9-cpqp","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-8phw-xrj9-cpqp","identifiers":["GHSA-8phw-xrj9-cpqp","CVE-2026-75523"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
