Prior to 2.63.6, a low-privileged authenticated user of filebrowser (with create + delete permissions in their own isolated scope) can silently destroy share-link records belonging to any other user — including the administrator — by performing a legitimate DELETE on a file in their own directory whose logical path happens to be a byte-prefix of another user's stored share.Link.Path. The file contents of the victim are not exposed, but the victim's share links are irrevocably wiped. This vulnerability is fixed in 2.63.6.","published_at":"2026-06-25T17:40:18.235000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":7.2,"cvss_v4_vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N","cvss_v4_severity":"HIGH","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-639"],"nvd_references":["https://github.com/filebrowser/filebrowser/security/advisories/GHSA-5ww9-jg6q-38r7","https://github.com/filebrowser/filebrowser/commit/0231b7ebdfbe77a6c54027d30c4856c3fd81ee4d","https://github.com/filebrowser/filebrowser/releases/tag/v2.63.6"],"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":"2026-06-28T17:55:37.240342Z","updated_at":"2026-06-28T23:30:53.764986Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"AT","name":"Attack Requirements","value":"N","value_label":"None"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"N","value_label":"None"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"H","value_label":"High"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"N","value_label":"None"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"N","value_label":"None"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"}]},"affected":[{"vendor_slug":"filebrowser","vendor_name":"filebrowser","product_slug":"filebrowser","product_name":"filebrowser","version_start":"< 2.63.6","version_start_inclusive":true,"version_end":"< 2.63.6","version_end_inclusive":true,"cpe23_uri":"cve5:filebrowser:filebrowser:< 2.63.6:< 2.63.6"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/filebrowser/filebrowser/security/advisories/GHSA-5ww9-jg6q-38r7","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/filebrowser/filebrowser/commit/0231b7ebdfbe77a6c54027d30c4856c3fd81ee4d","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/filebrowser/filebrowser/releases/tag/v2.63.6","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-06-25T17:40:18.235000Z","label":"CVE published","source":null}]}
