{"schema":"threatline.record/2","record":{"id":"CVE-2026-103028","aliases":["GHSA-wwv9-g5x4-966q","GO-2026-6802"],"summary":"SFTPGo source-side file-pattern filter bypass during copy operations","details":"### Summary\n\nFile pattern filters (`denied_patterns` / `allowed_patterns`) were evaluated on the destination of a copy only. A user holding the copy permission could copy a file denied by the filters to a permitted name and then read it. A recursive directory copy reproduced the contents of a restricted directory under a path where the filters do not deny them, and the hide policy was affected in the same way: a file reported as missing by stat and by directory listings could still be copied.\n\n### Details\n\nAn authenticated user can read the contents of files that the file pattern filters are configured to deny them. Nothing else is bypassed: the home directory, the virtual folder layout and the per-directory permissions are all still enforced, and both ends of the copy are paths the account can already reach. No access to other accounts and no administrative capability.","categories":["Libraries & packages"],"product":"github.com/drakkan/sftpgo/v2","vendor":"drakkan","ecosystem":"go","affected_ranges":[{"source":"GitHub Advisory Database","source_url":"https://github.com/advisories/GHSA-wwv9-g5x4-966q","source_modified_at":"2026-10-15T20:22:12Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"ecosystem":"go","name":"github.com/drakkan/sftpgo/v2"},"range":">= 2.5.0, <= 2.7.5"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-103028","source_modified_at":"2026-10-14T14:58:43.810Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"sftpgo","vendor":"drakkan","versions":[{"version":">= 2.5.0, < 2.7.6","status":"affected"}],"defaultStatus":null},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-wwv9-g5x4-966q","source_modified_at":"2026-10-19T21:41:22.513452094Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"github.com/drakkan/sftpgo/v2","ecosystem":"Go","purl":"pkg:golang/github.com/drakkan/sftpgo/v2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.5.0"},{"fixed":"2.7.6"}]}],"versions":[]}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/advisories/GHSA-wwv9-g5x4-966q","source_modified_at":"2026-10-15T20:22:12Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"ecosystem":"go","name":"github.com/drakkan/sftpgo/v2"},"version":"2.7.6"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-wwv9-g5x4-966q","source_modified_at":"2026-10-19T21:41:22.513452094Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"github.com/drakkan/sftpgo/v2","ecosystem":"Go","purl":"pkg:golang/github.com/drakkan/sftpgo/v2"},"version":"2.7.6"}],"cvss":4.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00219,"percentile":0.11711,"score_date":"2026-10-23"},"published_at":"2026-10-13T14:54:47.246Z","modified_at":"2026-10-19T21:41:22.513452094Z","provenance":[{"source":"GitHub Advisory Database","url":"https://github.com/advisories/GHSA-wwv9-g5x4-966q","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-15T20:22:12Z"},{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-103028","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-14T14:58:43.810Z"},{"source":"OSV","url":"https://osv.dev/vulnerability/GHSA-wwv9-g5x4-966q","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T21:41:22.513452094Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-103028","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["GitHub Advisory Database","CVE List","OSV","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/drakkan/sftpgo/security/advisories/GHSA-wwv9-g5x4-966q","tags":["x_refsource_CONFIRM"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-103028","source":"GitHub Advisory Database"},{"source":"CVE List","url":"https://github.com/drakkan/sftpgo/commit/dc8886bc079094b4ac2338df683f358b7676b5eb","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/drakkan/sftpgo/releases/tag/v2.7.6","tags":["x_refsource_MISC"]},{"url":"https://github.com/advisories/GHSA-wwv9-g5x4-966q","source":"GitHub Advisory Database"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-14T14:58:17.350907Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"ecosystem","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-19T21:41:22.513452094Z","content_hash":"d5e28afd89e333229fb399486c9268b90b634dae2f35370d6ce31d0aadb9b803"}}
