{"id":"CVE-2025-48494","aliases":["GHSA-95rc-wc32-gm53","GO-2025-3737"],"url":"https://o3.security/vulnerability/CVE-2025-48494","summary":"Gokapi vulnerable to stored XSS via uploading file with malicious file name","details":"### Impact\n\nWhen using end-to-end encryption, a stored XSS vulnerability can be exploited by uploading a file with JavaScript code embedded in the filename. After upload and every time someone opens the upload list, the script is then parsed.\n\nWith the affected versions <v2.0, there was no user permission system implemented, therefore all authenticated users were already able to see and modify all resources, even if end-to-end encrypted, as the encryption key had to be the same for all users with <v2.0. Nethertheless with XSS, other attack vectors like redirection or crypto mining would be possble.\n\n### Patches\n\nThis CVE has been fixed in v2.0.0\n\n### Workarounds\n\nIf you are the only authenticated user using Gokapi, you are not affected. A workaround would be to disable end-to-end encryption.","published":"2025-06-02T11:03:52.689Z","modified":"2026-08-12T03:51:43.237607781Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/forceu/gokapi","fixedVersion":null},{"ecosystem":"Go","name":"github.com/forceu/gokapi","fixedVersion":"0.0.0-20250530191232-343cc566cfd7"}],"fix":{"url":"https://github.com/Forceu/Gokapi/commit/343cc566cfd7f4efcd522c92371561d494aed6b0","label":"Forceu/Gokapi@343cc56"},"references":[{"type":"WEB","url":"https://github.com/Forceu/Gokapi/releases/tag/v2.0.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/48xxx/CVE-2025-48494.json"},{"type":"ADVISORY","url":"https://github.com/Forceu/Gokapi/security/advisories/GHSA-95rc-wc32-gm53"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-48494"},{"type":"FIX","url":"https://github.com/Forceu/Gokapi/commit/343cc566cfd7f4efcd522c92371561d494aed6b0"},{"type":"PACKAGE","url":"https://github.com/Forceu/Gokapi"},{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2025-3737"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:43.237607781Z"}}
