Prior to versions 1.1.3-stable and 1.2.6-beta, when users share password-protected files, the recipient can completely bypass the password and still download the file. This happens because the API returns a direct download link in the details of the share, which is accessible to anyone with JUST THE SHARE LINK, even without the password. Versions 1.1.3-stable and 1.2.6-beta fix the issue.","published_at":"2026-02-25T02:24:48.357000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":7.1,"cvss_v4_vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:L/VA:N/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-200","CWE-288","CWE-287"],"nvd_references":["https://github.com/gtsteffaniak/filebrowser/security/advisories/GHSA-8vrh-3pm2-v4v6","https://github.com/gtsteffaniak/filebrowser/commit/c51b0ee9738fa4599b409f47c5bf820ef31b4fe1"],"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":"2026-06-28T23:29:32.765824Z"},"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":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"P","value_label":"Passive"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"L","value_label":"Low"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"N","value_label":"None"},{"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":"gtsteffaniak","vendor_name":"gtsteffaniak","product_slug":"filebrowser","product_name":"filebrowser","version_start":"< 1.1.3-stable","version_start_inclusive":true,"version_end":"< 1.1.3-stable","version_end_inclusive":true,"cpe23_uri":"cve5:gtsteffaniak:filebrowser:< 1.1.3-stable:< 1.1.3-stable"},{"vendor_slug":"gtsteffaniak","vendor_name":"gtsteffaniak","product_slug":"filebrowser","product_name":"filebrowser","version_start":">= 1.2.0-beta, < 1.2.6-beta","version_start_inclusive":true,"version_end":">= 1.2.0-beta, < 1.2.6-beta","version_end_inclusive":true,"cpe23_uri":"cve5:gtsteffaniak:filebrowser:>= 1.2.0-beta, < 1.2.6-beta:>= 1.2.0-beta, < 1.2.6-beta"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/gtsteffaniak/filebrowser/security/advisories/GHSA-8vrh-3pm2-v4v6","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/gtsteffaniak/filebrowser/commit/c51b0ee9738fa4599b409f47c5bf820ef31b4fe1","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-02-25T02:24:48.357000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:52:22.671512Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:52:22.671512Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:52:22.671512Z","label":"CVSS score revised","source":"cvelistv5"}]}
