{"id":"CVE-2026-75523","summary":"Steeltoe.Management.Endpoint: HttpExchanges URI masking leaks query-string secrets","details":"Steeltoe is an open source project that provides a collection of libraries that helps users build cloud-native applications. 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.","aliases":["GHSA-8phw-xrj9-cpqp"],"modified":"2026-09-19T03:47:28.235684882Z","published":"2026-09-17T15:35:01.362Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-200"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/75xxx/CVE-2026-75523.json"},"references":[{"type":"WEB","url":"https://github.com/SteeltoeOSS/Steeltoe/releases/tag/4.3.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/75xxx/CVE-2026-75523.json"},{"type":"ADVISORY","url":"https://github.com/SteeltoeOSS/security-advisories/security/advisories/GHSA-8phw-xrj9-cpqp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-75523"},{"type":"FIX","url":"https://github.com/SteeltoeOSS/Steeltoe/commit/9bf0ecb9f2d4a34b65f61d41c5625d49071ae9fa"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/steeltoeoss/steeltoe","events":[{"introduced":"0"},{"fixed":"9bf0ecb9f2d4a34b65f61d41c5625d49071ae9fa"},{"fixed":"a56a5e5a324a1581cbfcdf726dbca3e25b604f86"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"4.3.0"}]}}],"versions":["4.2.0","4.1.0","4.0.0","4.0.0-rc1","4.0.0-beta1","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/cve-osv-conversion/osv-output/CVE-2026-75523.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
