{"id":"CVE-2023-38493","aliases":["GHSA-wvp2-9ppw-337j"],"url":"https://o3.security/vulnerability/CVE-2023-38493","summary":"Paths contain matrix variables bypass decorators","details":"Armeria is a microservice framework Spring supports Matrix variables. When Spring integration is used, Armeria calls Spring controllers via `TomcatService` or `JettyService` with the path that may contain matrix variables. Prior to version 1.24.3, the Armeria decorators might not invoked because of the matrix variables. If an attacker sends a specially crafted request, the request may bypass the authorizer. Version 1.24.3 contains a patch for this issue.","published":"2023-07-25T20:51:11.170Z","modified":"2026-08-08T08:26:43.824629Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"com.linecorp.armeria:armeria","fixedVersion":"1.24.3"}],"fix":{"url":"https://github.com/line/armeria/commit/039db50bbfc88014ea8737fd1e1ddd6fd3fc4f07","label":"line/armeria@039db50"},"references":[{"type":"WEB","url":"https://docs.spring.io/spring-framework/reference/web/webmvc/mvc-controller/ann-methods/matrix-variables.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/38xxx/CVE-2023-38493.json"},{"type":"ADVISORY","url":"https://github.com/line/armeria/security/advisories/GHSA-wvp2-9ppw-337j"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-38493"},{"type":"FIX","url":"https://github.com/line/armeria/commit/039db50bbfc88014ea8737fd1e1ddd6fd3fc4f07"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-08T08:26:43.824629Z"}}
