Prior to 4.3.0, the Steeltoe.Management.Endpoint /actuator/httpexchanges endpoint passes recorded request URIs through MaskedUri, which masks URI user information but does not inspect query strings. When Management:Endpoints:HttpExchanges:IncludeQueryString is enabled, the HttpExchangeRequest response can disclose OAuth tokens, password-reset tokens, signed-URL signatures, API keys, and other query-string secrets from prior traffic to a caller that can reach the explicitly exposed endpoint. The Steeltoe.Management.Endpoint.Actuators.HttpExchanges DEBUG logger also records these URIs, creating a second disclosure channel for users with log access. This issue is fixed in version 4.3.0.","published":"2026-09-17T16:17:41.773","modified":"2026-09-17T16:17:41.773","cvss":{"score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/SteeltoeOSS/Steeltoe/commit/9bf0ecb9f2d4a34b65f61d41c5625d49071ae9fa","label":"SteeltoeOSS/Steeltoe@9bf0ecb"},"references":[{"type":"WEB","url":"https://github.com/SteeltoeOSS/Steeltoe/commit/9bf0ecb9f2d4a34b65f61d41c5625d49071ae9fa"},{"type":"WEB","url":"https://github.com/SteeltoeOSS/Steeltoe/releases/tag/4.3.0"},{"type":"WEB","url":"https://github.com/SteeltoeOSS/security-advisories/security/advisories/GHSA-8phw-xrj9-cpqp"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-17T16:17:41.773"}}
