{"id":"CVE-2026-56678","summary":"9Router: Kiro region injection allows authenticated SSRF with Authorization header forwarding","details":"9Router is an AI router & token saver. Prior to 0.5.6, the Kiro API-key validation endpoint POST /api/oauth/kiro/api-key builds an upstream URL using a user-controlled region value, allowing an authenticated attacker to supply a crafted region such as kiro-canary.local:8443# and cause 9Router to send the Kiro validation request to an attacker-controlled host while forwarding the submitted Kiro API key as an Authorization header. This issue is fixed in version 0.5.6.","aliases":["GHSA-6mwv-4mrm-5p3m"],"modified":"2026-07-18T03:42:07.753555839Z","published":"2026-07-15T20:51:33.190Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-20","CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/56xxx/CVE-2026-56678.json"},"references":[{"type":"WEB","url":"https://github.com/decolua/9router/releases/tag/v0.5.6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/56xxx/CVE-2026-56678.json"},{"type":"ADVISORY","url":"https://github.com/decolua/9router/security/advisories/GHSA-6mwv-4mrm-5p3m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-56678"},{"type":"FIX","url":"https://github.com/decolua/9router/commit/126aa244c5b51b74ab8c7594e3418fcf4437bf6f"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/decolua/9router","events":[{"introduced":"0"},{"fixed":"126aa244c5b51b74ab8c7594e3418fcf4437bf6f"},{"fixed":"584cf66a70a99dd9b400cbfaf72b98066c4e633d"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.5.6"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v0.5.4","v0.5.2","v0.4.80","v0.4.71","v0.4.66","v0.4.63","v0.4.62","v0.4.59","v0.4.58","v0.4.55","v0.4.52","v0.4.50","v0.4.49","v0.4.46","v0.4.44","v0.4.41","v0.4.39","v0.4.38","v0.4.37","v0.4.36","v0.4.33","v0.4.31","v0.4.30","v0.4.29","v0.4.28","v0.4.27","v0.4.25","v0.4.20","v0.4.19","v0.4.18","v0.4.16","v0.4.14","v0.4.13","v0.4.12","v0.4.11","v0.4.10","v0.4.8","v0.4.6","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.3.98","v0.3.97","v0.3.91","v0.3.90","v0.3.89","v0.3.87","v0.3.86","v0.3.83","v0.3.75","v0.3.47","v0.3.42","v0.3.34","v0.3.17","v0.2.89","v0.2.79","v0.2.71","v0.2.70","v0.2.67","v0.2.56","v0.2.52","v0.2.43","v0.2.36","v0.2.31","v0.2.27","v0.2.21"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-56678.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"}]}
