{"id":"CVE-2026-33431","summary":"Roxy-WI Vulnerable to Authenticated Arbitrary File Read via Path Traversal in Config Version Viewer","details":"Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. Prior to version 8.2.6.4, the POST /config/\u003cservice\u003e/show API endpoint accepts a configver parameter that is directly appended to a base directory path to construct a local file path, which is subsequently opened and its contents returned to the caller. The existing path traversal guard only inspects the base directory variable (which is never user-controlled) and entirely ignores the user-supplied configver value. An authenticated attacker can supply a configver value containing `../` sequences to escape the intended directory and read arbitrary files accessible to the web application process. Version 8.2.6.4 contains a patch for the issue.","aliases":["GHSA-w3c9-36jf-qrw4"],"modified":"2026-07-15T01:49:10.183474202Z","published":"2026-04-20T20:24:15.319Z","database_specific":{"cwe_ids":["CWE-24"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33431.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33431.json"},{"type":"ADVISORY","url":"https://github.com/roxy-wi/roxy-wi/security/advisories/GHSA-w3c9-36jf-qrw4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33431"},{"type":"FIX","url":"https://github.com/roxy-wi/roxy-wi/commit/d4d100067dd0ee04317f05d3b51be8fcfdc3f802"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/roxy-wi/roxy-wi","events":[{"introduced":"0"},{"fixed":"d72ea494d0bf1ee220fe141625a4298600f624ad"},{"fixed":"d4d100067dd0ee04317f05d3b51be8fcfdc3f802"}],"database_specific":{"cpe":"cpe:2.3:a:roxy-wi:roxy-wi:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"8.2.6.4"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["v8.2.6.3","v8.2.8.2","v8.2.8.1","v8.2.6","v8.2.5","v8.2.4","v8.2.3","v8.2.2","v8.2.1","v8.2.0","v8.1.8","v8.1.7","v8.1.6","v8.1.5","v8.1.4","v8.1.3","v8.1.2","v8.1.1","v8.1.0.1","v8.1","v8.0.2","v8.0.1","v8.0","v7.3.2.0","v7.3.1.0","v7.3.0.0","v7.2.6.0","v7.2.5.0","v7.2.4.0","v7.2.3.0","v7.2.2.0","v7.2.1.0","v7.2.0.0","v7.1.2.0","v7.1.1.0","v7.1.0.0","v7.0.4.0","v7.0.3.0","v7.0.2.0","v7.0.1.0","v7.0.0.0","v6.3.19.0","v6.3.18.0","v6.3.17.0","v6.3.16.0","v6.3.15.0","v6.3.14.0","v6.3.13.0","v6.3.12.0","v6.3.11.0","v6.3.10.0","v6.3.9.0","v6.3.8.0","v6.3.7.0","v6.3.6.0","v6.3.5.0","v6.3.4.0","v6.3.3.0","v6.3.2.0","v6.3.1.0","v6.3.0.0","v6.2.3.0","v6.2.2.0","v6.2.1.0","v6.2.0.0","v6.1.5.0","v6.1.4.0","v6.1.3.0","v6.1.2.0","v6.1.1.0","v6.1.0.0","v6.0.3.0","v6.0.2.0","v6.0.1.0","v6.0.0.0","v5.5.1.0","v5.5.0.0","v5.4.3.0","v5.4.2.0","v5.4.1.0","v5.4.0.0","v5.3.6.0","v.5.3.5.0","v5.3.4.0","v5.3.3.0","v5.3.2.0","v5.3.1.0","v5.3.0.0","v5.2.6.0","v5.2.5.0","v5.2.4.0","v5.2.3.0","v5.2.2.0","v5.2.1","v5.2.0","v5.1.4.0","v5.1.1.0","v4.4.1.0","3.4.5.1","3.4.5","3.4.4.7","3.4.4.6","v3.3","v3.2.13","v2.0.2","v1.10.2.1","v1.10.2","v1.10.1","v1.10","v1.9.1","v1.6","v1.4.1","v1.4","v1.3","v1.1","v1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33431.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:P"}]}
