{"id":"CVE-2026-55846","aliases":["GHSA-82cg-3hv7-74gc"],"url":"https://o3.security/vulnerability/CVE-2026-55846","summary":"Allure: Path Traversal in Allure Report HTTP Server Allows Arbitrary File Read","details":"Allure 2 is the version 2.x branch of Allure Report, a multi-language test reporting tool. Prior to 2.39.0, the HTTP server started by allure serve and allure open uses URI.getPath() in Commands.setUpServer() in allure-commandline/src/main/java/io/qameta/allure/Commands.java and passes the percent-decoded request path to reportDirectory.resolve() without normalizing the result or confirming that it remains inside that directory. An unauthenticated client that can reach the server can submit parent-directory segments, including percent-encoded segments, and cause serveFile() to return any regular file readable by the Allure process. The server binds to localhost by default, but the --host option can expose it to other systems, and local users, adjacent containers, or browser-origin attacks may reach a local listener. This can disclose credentials, configuration, source code, build secrets, and other CI/CD data. This issue is fixed in version 2.39.0.","published":"2026-09-14T17:20:49.131Z","modified":"2026-09-16T08:05:57.811088Z","cvss":{"score":6.2,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Maven","name":"io.qameta.allure:allure-commandline","fixedVersion":"2.39.0"}],"fix":{"url":"https://github.com/allure-framework/allure2/commit/e83cd67658bc2266832ab366eadd0bc1f48baced","label":"allure-framework/allure2@e83cd67"},"references":[{"type":"WEB","url":"https://github.com/allure-framework/allure2/releases/tag/2.39.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55846.json"},{"type":"ADVISORY","url":"https://github.com/allure-framework/allure2/security/advisories/GHSA-82cg-3hv7-74gc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55846"},{"type":"FIX","url":"https://github.com/allure-framework/allure2/commit/e83cd67658bc2266832ab366eadd0bc1f48baced"},{"type":"FIX","url":"https://github.com/allure-framework/allure2/pull/3288"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-16T08:05:57.811088Z"}}
