{"id":"CVE-2026-110726","published":"2026-10-15T12:16:37.517","lastModified":"2026-10-15T16:17:46.283","description":"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.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-348","CWE-770","CWE-807"],"vendors":[],"products":[],"references":[{"url":"https://github.com/eclipse-ecsp/api-gateway/pull/330","tags":[]},{"url":"https://github.com/eclipse-ecsp/api-gateway/security/advisories/GHSA-ch6x-rg7q-7jfx","tags":[]},{"url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/404","tags":[]}],"exploitRefs":[{"url":"https://github.com/eclipse-ecsp/api-gateway/pull/330","tags":[]},{"url":"https://github.com/eclipse-ecsp/api-gateway/security/advisories/GHSA-ch6x-rg7q-7jfx","tags":[]}],"hasPoc":true,"ai":null}
