{"id":"CVE-2026-28674","state":"PUBLISHED","title":"xiaoheiFS Vulnerable to RCE via Arbitrary Payment Plugin Upload (Automatic Execution)","description":"xiaoheiFS is a self-hosted financial and operational system for cloud service businesses. In versions up to and including 0.3.15, the `AdminPaymentPluginUpload` endpoint lets admins upload any file to `plugins/payment/`. It only checks a hardcoded password (`qweasd123456`) and ignores file content. A background watcher (`StartWatcher`) then scans this folder every 5 seconds. If it finds a new executable, it runs it immediately, resulting in RCE. Version 4.0.0 fixes the issue.","publishedAt":"2026-03-18T00:48:39.652Z","updatedAt":"2026-03-18T14:34:00.955Z","severity":{"score":7.2,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["danvei233 xiaoheiFS"],"affected":[{"vendor":"danvei233","product":"xiaoheiFS","versions":[{"version":"< 0.4.0","status":"affected"}]}],"references":["https://github.com/danvei233/xiaoheiFS/security/advisories/GHSA-hcj4-gfvq-qv4p"],"weaknesses":["CWE-434","CWE-798"],"ingestedAt":"2026-10-29T20:11:31.369Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/28xxx/CVE-2026-28674.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-28674","state":"PUBLISHED","datePublished":"2026-03-18T00:48:39.652Z","dateUpdated":"2026-03-18T14:34:00.955Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-03-02T21:43:19.926Z"},"containers":{"cna":{"title":"xiaoheiFS Vulnerable to RCE via Arbitrary Payment Plugin Upload (Automatic Execution)","descriptions":[{"lang":"en","value":"xiaoheiFS is a self-hosted financial and operational system for cloud service businesses.
