{"identifier":"CVE-2026-110723","cve":{"id":"CVE-2026-110723","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.","published":"2026-10-15T13:17:12.857000+00:00","modified":"2026-10-15T14:41:34.110000+00:00","status":"Awaiting Analysis","score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cvss_version":"3.1","affected":[],"weaknesses":["CWE-290","CWE-644"],"references":[{"url":"https://github.com/eclipse-ecsp/api-gateway/pull/330","source":"emo@eclipse.org"},{"url":"https://github.com/eclipse-ecsp/api-gateway/security/advisories/GHSA-m468-w7pr-f39w","source":"emo@eclipse.org"},{"url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/406","source":"emo@eclipse.org"}],"kev":null,"kev_checked":true,"metrics":{"cvssMetricV31":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-15T13:11:09.309966Z","id":"CVE-2026-110723","options":[{"exploitation":"none"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"configurations":[],"source":"nvd","retrieved_at":"2026-10-28T10:22:39.366600+00:00","exploited":false,"kev_stale":false,"products":[],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence."]},"epss":{"probability":0.00337,"percentile":0.27038,"date":"2026-10-28","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"github.com","source_url":"https://github.com/eclipse-ecsp/api-gateway/pull/330","investigate_url":"https://investigate.aeglixmind.com/#github.com"},{"domain":"gitlab.eclipse.org","source_url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/406","investigate_url":"https://investigate.aeglixmind.com/#gitlab.eclipse.org"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-110723","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-110723","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-110723","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
