CVE-2026-72903
HighCVSS 8.1Exploitation Probability (EPSS)
Low risk24th percentile - higher than 24% of all known CVEs
Summary
Tabby (formerly Terminus) before version 1.0.235 contains a path traversal vulnerability via a malicious SFTP server. The server can return filenames with backslashes, which are interpreted as path separators on Windows, allowing files to be created or overwritten outside the selected directory.
Risk Assessment
An attacker can create or overwrite arbitrary files on Windows with the privileges of the Tabby user, potentially leading to system compromise or data corruption.
Recommendation
Update Tabby to version 1.0.235 or later, which includes the fix.
Original NVD description (English source)
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.
