{"id":"CVE-2026-110723","details":"In `api-gateway` versions till `1.7.3`, The default rate-limit key resolver, `ClientIpKeyResolver`, derives the per-client bucket key from the leftmost element of the `X-Forwarded-For` request header. That element is supplied by the originating HTTP client and is not validated against any trusted-proxy list. A single attacker can therefore obtain an unlimited number of independent rate-limit buckets — one per unique header value — and completely bypass the gateway's request-rate limiting on every route that uses the shipped default configuration.","aliases":["GHSA-m468-w7pr-f39w"],"modified":"2026-10-17T02:48:12.214279895Z","published":"2026-10-15T12:14:08.140Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110723.json","cna_assigner":"eclipse","cwe_ids":["CWE-290","CWE-644"]},"references":[{"type":"WEB","url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/406"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110723.json"},{"type":"ADVISORY","url":"https://github.com/eclipse-ecsp/api-gateway/security/advisories/GHSA-m468-w7pr-f39w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110723"},{"type":"FIX","url":"https://github.com/eclipse-ecsp/api-gateway/pull/330"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/eclipse-ecsp/api-gateway","events":[{"introduced":"caea0f89d70317ac5e5a671c15e0c8c952730b60"},{"last_affected":"14e30b93bae820aa35a19e76372fd3cf1a8ab66e"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"1.1.1"},{"last_affected":"1.7.3"}]}}],"versions":["1.7.3","1.7.2","1.7.1","1.5.4","1.7.0","1.7.0-M1.1","1.6.2","1.6.1","1.6.0","1.5.1","1.5.3","1.5.2","1.5.0","1.4.0","1.4.0-M2","1.4.0-M1","1.3.4","1.3.3","1.3.2","1.3.1","1.3.0","1.3.0-M1.2","1.3.0-M1.1","1.3.0-M1","1.2.3","1.2.2","1.2.1","1.2.0-M2","1.2.0","1.2.0-M1","1.1.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-110723.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
