{"id":"CVE-2026-33528","aliases":["GHSA-4753-cmc8-8j9v","GO-2026-4817"],"url":"https://o3.security/vulnerability/CVE-2026-33528","summary":"GoDoxy has a Path Traversal Vulnerability in its File API","details":"GoDoxy is a reverse proxy and container orchestrator for self-hosters. Prior to version 0.27.5, the file content API endpoint at `/api/v1/file/content` is vulnerable to path traversal. The `filename` query parameter is passed directly to `path.Join(common.ConfigBasePath, filename)` where `ConfigBasePath = \"config\"` (a relative path). No sanitization or validation is applied beyond checking that the field is non-empty (`binding:\"required\"`). An authenticated attacker can use `../` sequences to read or write files outside the intended `config/` directory, including TLS private keys, OAuth refresh tokens, and any file accessible to the container's UID. Version 0.27.5 fixes the issue.","published":"2026-03-26T19:24:50.452Z","modified":"2026-08-12T03:51:11.310643464Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/yusing/godoxy","fixedVersion":"0.27.5"}],"fix":{"url":"https://github.com/yusing/godoxy/commit/a541d75bb50f1b542c096d8bc8082c3549f5c059","label":"yusing/godoxy@a541d75"},"references":[{"type":"WEB","url":"https://github.com/yusing/godoxy/releases/tag/v0.27.5"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33528.json"},{"type":"ADVISORY","url":"https://github.com/yusing/godoxy/security/advisories/GHSA-4753-cmc8-8j9v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33528"},{"type":"FIX","url":"https://github.com/yusing/godoxy/commit/a541d75bb50f1b542c096d8bc8082c3549f5c059"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:11.310643464Z"}}
