{"schemaVersion":3,"id":"CVE-2026-110724","aliases":[],"status":"published","duplicateOf":null,"title":null,"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.","dates":{"published":"2026-10-15T12:11:22.470Z","modified":"2026-10-16T18:43:57.741Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.5,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00272,"percentile":0.18318,"severity":"low","asOf":"2026-10-18T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-16T00:00:00.000Z","score":0.00155,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00272,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00272,"percentile":0.18318}],"last30":[{"date":"2026-10-16T00:00:00.000Z","score":0.00155,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00272,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00272,"percentile":0.18318}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-269","name":"Improper Privilege Management","description":"The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.","type":"weakness","status":"Draft","abstraction":"Class","likelihoodOfExploit":"Medium","url":"https://cwe.mitre.org/data/definitions/269.html"},{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key","description":"The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.","type":"weakness","status":"Incomplete","abstraction":"Base","likelihoodOfExploit":"High","url":"https://cwe.mitre.org/data/definitions/639.html"},{"id":"CWE-863","name":"Incorrect Authorization","description":"The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.","type":"weakness","status":"Incomplete","abstraction":"Class","likelihoodOfExploit":"High","url":"https://cwe.mitre.org/data/definitions/863.html"}],"affected":[{"vendor":"eclipse foundation","product":"eclipse connected services platform","name":"Eclipse Connected Services Platform","label":"eclipse connected services platform","ecosystem":null,"cpePart":"a","purl":null,"purlType":null,"versions":[{"text":"≥ 1.1.1, ≤ 1.7.3","noFixRecorded":false,"fixedIn":null}],"versionsText":"≥ 1.1.1, ≤ 1.7.3","eol":null,"hubHref":"/vendor/eclipse_foundation/eclipse_connected_services_platform"}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://github.com/eclipse-ecsp/api-gateway/pull/330","label":"github.com/eclipse-ecsp/api-gateway/pull/330","hostname":"github.com","tags":[]},{"url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/405","label":"gitlab.eclipse.org/security/cve-assignment/-/work_items/405","hostname":"gitlab.eclipse.org","tags":[]},{"url":"https://github.com/eclipse-ecsp/api-gateway/security/advisories/GHSA-4j9j-mx7g-p9p6","label":"github.com/eclipse-ecsp/api-gateway/security/advisories/GHSA-4j9j-mx7g-p9p6","hostname":"github.com","tags":[]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2026-10-15T12:11:22.470Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-10-16T18:43:57.741Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":30,"level":"medium","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-19T09:03:47.982Z","stale":false,"partial":false}}
