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.","categories":["Unclassified"],"product":"Eclipse Connected Services Platform","vendor":"Eclipse Foundation","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-110726","source_modified_at":"2026-10-15T15:30:14.212Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Eclipse Connected Services Platform","vendor":"Eclipse Foundation","versions":[{"status":"affected","version":"1.5.4","lessThanOrEqual":"1.7.3","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00192,"percentile":0.08397,"score_date":"2026-10-23"},"published_at":"2026-10-15T11:58:03.903Z","modified_at":"2026-10-15T15:30:14.212Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-110726","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T15:30:14.212Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-110726","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/eclipse-ecsp/api-gateway/pull/330"},{"source":"CVE List","url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/404"},{"source":"CVE List","url":"https://github.com/eclipse-ecsp/api-gateway/security/advisories/GHSA-ch6x-rg7q-7jfx"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CISA ADP","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-15T15:30:07.394578Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-15T15:30:14.212Z","content_hash":"09bf6789fc8134cfb333dad54118af2ec0837651731e1c281ef20b9801bea418"}}
