From 2.63.6 to 2.63.16, File Browser's archive builder uses strings.ReplaceAll(nameInArchive, \"\\\", \"/\"), which turns a POSIX filename such as ..\\..\\evil.sh into the archive entry ../../evil.sh, allowing a user with upload permission to plant a backslash-named file that escapes the extraction directory when another user downloads and extracts the generated zip or tar archive. This issue is fixed in version 2.63.17.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:N/I:H/A:N","score":6.8},"cwes":["CWE-22","CWE-23"],"references":["https://github.com/filebrowser/filebrowser/commit/8503ba61ff51d48a7313896483d130eb6a5abfe0","https://github.com/filebrowser/filebrowser/releases/tag/v2.63.17","https://github.com/filebrowser/filebrowser/security/advisories/GHSA-83xp-526h-j3ww","https://github.com/filebrowser/filebrowser/security/advisories/GHSA-83xp-526h-j3ww"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:45:36.895656543+00:00"},"epss":{"cve":"CVE-2026-62843","score":0.00391,"percentile":0.33285,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-83xp-526h-j3ww","url":"https://osv.dev/vulnerability/GHSA-83xp-526h-j3ww","summary":"File Browser: Archive builder turns backslash filenames into path traversal (zip-slip)","modified":"2026-07-22T21:11:44.557134742Z","packages":[{"ecosystem":"Go","name":"github.com/filebrowser/filebrowser/v2","purl":"pkg:golang/github.com/filebrowser/filebrowser/v2","ranges":[">=2.63.6 <2.63.17"],"fixed":["2.63.17"]}]},{"id":"GO-2026-6026","url":"https://osv.dev/vulnerability/GO-2026-6026","summary":"File Browser: Archive builder turns backslash filenames into path traversal (zip-slip) in github.com/filebrowser/filebrowser","modified":"2026-07-22T21:00:25.556738677Z","packages":[{"ecosystem":"Go","name":"github.com/filebrowser/filebrowser","purl":"pkg:golang/github.com/filebrowser/filebrowser","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/filebrowser/filebrowser/v2","purl":"pkg:golang/github.com/filebrowser/filebrowser/v2","ranges":[">=2.63.6 <2.63.17"],"fixed":["2.63.17"]}]}],"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).
