The authentication bypass occurs when Shiro and Spring Boot are using different pattern-matching techniques. Both Shiro and Spring Boot < 2.6 default to Ant style pattern matching. Mitigation: Update to Apache Shiro 1.11.0, or set the following Spring Boot configuration value: `spring.mvc.pathmatch.matching-strategy = ant_path_matcher`","dates":{"published":"2023-01-14T10:15:00.000Z","modified":"2026-02-04T03:16:45.809Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.5,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"OSV · Ubuntu","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","computed":true,"selection":"version-preference"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"OSV · Ubuntu","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":10,"impact":6,"computed":true}]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"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":[],"affected":[{"vendor":"ubuntu","product":"shiro","name":"shiro","label":"shiro","ecosystem":"Ubuntu","cpePart":null,"purl":"pkg:deb/ubuntu/shiro","purlType":"deb","versions":[{"text":"All versions","noFixRecorded":true,"fixedIn":null}],"versionsText":"All versions (No fix recorded)","eol":null,"hubHref":null}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://ubuntu.com/security/CVE-2023-22602","label":"ubuntu.com/security/CVE-2023-22602","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://lists.apache.org/thread/dzj0k2smpzzgj6g666hrbrgsrlf9yhkl","label":"lists.apache.org/thread/dzj0k2smpzzgj6g666hrbrgsrlf9yhkl","hostname":"lists.apache.org","tags":["REPORT"]},{"url":"https://www.cve.org/CVERecord?id=CVE-2023-22602","label":"www.cve.org/CVERecord?id=CVE-2023-22602","hostname":"www.cve.org","tags":["REPORT"]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":["CVE-2023-22602"]},"timeline":[{"kind":"published","date":"2023-01-14T10:15:00.000Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-02-04T03:16:45.809Z","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":"2026-10-19T09:39:43.862Z","stale":false,"partial":false}}
