{"schemaVersion":3,"id":"CVE-2026-72903","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Tabby (formerly Terminus) is a highly configurable terminal emulator. Prior to 1.0.235, a malicious SFTP server can return a backslash traversal filename through entry.name. In tabby-ssh/src/session/sftp.ts, SFTPSession.readdir() and _makeFile() use POSIX path processing that preserves the backslashes as ordinary filename characters. In tabby-ssh/src/components/sftpPanel.component.ts, downloadFolderRecursive() propagates item.name into the local relative path. In tabby-electron/src/services/platform.service.ts, ElectronDirectoryDownload.createFile() passes that path to Windows-native path.join(), and in tabby-electron/src/sftpContextMenu.ts, EditSFTPContextMenu.edit() passes item.name to path.join() for the temporary edit path. Windows interprets the preserved backslashes and parent-directory components as traversal, allowing attacker-controlled content to be created or overwritten outside the selected download directory or temporary edit directory. This issue is fixed in version 1.0.235.","dates":{"published":"2026-08-10T20:39:57.054Z","modified":"2026-08-11T14:57:24.700Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":8.1,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":8.1,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":8.1,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00492,"percentile":0.41327,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0.12599999999999997,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.00366},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00366,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00366,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00366,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00366,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00366,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00366,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00366,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00366,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00366,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00366,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00492,"percentile":0.41327}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.00366,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00366,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00366,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00492,"percentile":null},{"date":"2026-10-10T00:00:
