{"schemaVersion":3,"id":"CVE-2026-94269","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Use of Non-Canonical URL paths for authorization decisions vulnerability in Apache APISIX.\n\n\n\nIn some configurations where a permissive route overlaps a protected one, a crafted encoded path can reach an upstream endpoint that the matched route's policies were never meant to cover. A request that should have been rejected is served instead, giving unauthenticated access to a protected upstream endpoint. This issue affects Apache APISIX: from 2.14.1 through 3.18.0.\n\n\n\nUsers are recommended to upgrade to version 3.19.0, which fixes the issue.","dates":{"published":"2026-10-01T11:02:20.117Z","modified":"2026-10-01T14:50:27.791Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.3,"severity":"medium","version":"4.0","versionLabel":"v4.0","source":"CVE.org","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"4.0","versionLabel":"v4.0","source":"CVE.org","score":6.3,"severity":"medium","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","exploitability":null,"impact":null,"computed":false},{"version":"4.0","versionLabel":"v4.0","source":"NVD","score":6.3,"severity":"medium","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00421,"percentile":0.3508,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-02T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00421,"percentile":0.3508}],"last30":[{"date":"2026-10-02T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00421,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00421,"percentile":0.3508}]},"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-647","name":"Use of Non-Canonical URL Paths for Authorization Decisions","description":"The product defines policy namespaces and makes authorization decisions based on the assumption that a URL is canonical.
