In versions 1.18.6 and below, when accessing the recent uploads page at `/?ru`, users can filter the results using an input field at the top. This field appends a filter parameter to the URL, which reflects its value directly into a `<script>` block without proper escaping, allowing for reflected Cross-Site Scripting (XSS) and can be exploited against both authenticated and unauthenticated users. This is fixed in version 1.18.7.","published_at":"2025-07-31T13:48:41.615000Z","last_modified_at":null,"cvss_v3_score":6.3,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-79","CWE-80"],"nvd_references":["https://github.com/9001/copyparty/security/advisories/GHSA-8mx2-rjh8-q3jq","https://github.com/9001/copyparty/commit/a8705e611d05eeb22be5d3d7d9ab5c020fe54c62","https://github.com/9001/copyparty/releases/tag/v1.18.7"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:27:34.949517Z"},"effective_severity":"MEDIUM","badges":["poc"],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"R","value_label":"Required"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"L","value_label":"Low"},{"metric":"I","name":"Integrity","value":"L","value_label":"Low"},{"metric":"A","name":"Availability","value":"L","value_label":"Low"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"9001","vendor_name":"9001","product_slug":"copyparty","product_name":"copyparty","version_start":"< 1.18.7","version_start_inclusive":true,"version_end":"< 1.18.7","version_end_inclusive":true,"cpe23_uri":"cve5:9001:copyparty:< 1.18.7:< 1.18.7"}],"exploit_refs":[{"source":"nuclei","kind":"nuclei","url":"https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2025/CVE-2025-54589.yaml","title":"Copyparty <=1.18.6 - Cross-Site Scripting","author":"s-cu-bot","disclosed_at":null}],"news":[],"references":[{"url":"https://github.com/9001/copyparty/security/advisories/GHSA-8mx2-rjh8-q3jq","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/9001/copyparty/commit/a8705e611d05eeb22be5d3d7d9ab5c020fe54c62","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/9001/copyparty/releases/tag/v1.18.7","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2025-07-31T13:48:41.615000Z","label":"CVE published","source":null},{"type":"poc_available","at":"2026-06-24T00:29:48.638073Z","label":"Public PoC available","source":"nuclei"},{"type":"cvss_changed","at":"2026-06-28T17:47:49.389331Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:47:49.389331Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:47:49.389331Z","label":"CVSS score revised","source":"cvelistv5"}]}
