Prior to version 1.8.7, the application contains a reflected cross-site scripting via URL-parameter `?k304=...` and `?setck=...`. The worst-case outcome of this is being able to move or delete existing files on the server, or upload new files, using the account of the person who clicks the malicious link. It is recommended to change the passwords of one's copyparty accounts, unless one have inspected one's logs and found no trace of attacks. Version 1.8.7 contains a patch for the issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["http://packetstormsecurity.com/files/173821/Copyparty-1.8.6-Cross-Site-Scripting.html","https://github.com/9001/copyparty/commit/007d948cb982daa05bc6619cd20ee55b7e834c38","https://github.com/9001/copyparty/security/advisories/GHSA-f54q-j679-p9hh","http://packetstormsecurity.com/files/173821/Copyparty-1.8.6-Cross-Site-Scripting.html","https://github.com/9001/copyparty/commit/007d948cb982daa05bc6619cd20ee55b7e834c38"],"products":["9001:copyparty"],"source":"nvd","synced_at":"2026-10-19T21:38:35.729974749+00:00"},"epss":{"cve":"CVE-2023-38501","score":0.09246,"percentile":0.95354,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-f54q-j679-p9hh","url":"https://osv.dev/vulnerability/GHSA-f54q-j679-p9hh","summary":"copyparty vulnerable to reflected cross-site scripting via k304 parameter","modified":"2025-09-04T16:43:29.302208Z","packages":[{"ecosystem":"PyPI","name":"copyparty","purl":"pkg:pypi/copyparty","ranges":["<1.8.7"],"fixed":["1.8.7"]}]},{"id":"PYSEC-2023-132","url":"https://osv.dev/vulnerability/PYSEC-2023-132","summary":"","modified":"2023-11-08T04:13:08.308948Z","packages":[{"ecosystem":"PyPI","name":"copyparty","purl":"pkg:pypi/copyparty","ranges":["<1.8.7"],"fixed":["1.8.7"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
