Vulnerability Title
Tabby: Drag-and-drop path injection still allows RCE via shell command substitution (incomplete fix for CVE-2026-45038)
Source: CVE Program / CVE List V5
Vulnerability 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.
