Tabby (formerly Terminus) is a highly configurable terminal emulator. Prior to 1.0.233, Tabby registers itself as the handler for the tabby:// URL scheme on all platforms. The URL scheme handler supports a run command that directly executes OS commands with no user confirmation, sanitization, or sandboxing. An attacker can craft a malicious link (tabby://run?command=...) and deliver it via a website, email, chat message, or any other medium. When a victim clicks the link, the OS launches Tabby which immediately spawns the specified command as a child process with the user's full privileges. This is a zero-click-after-link-visit RCE vulnerability. This vulnerability is fixed in 1.0.233.
AnalysisAI
Remote code execution in Tabby terminal emulator versions prior to 1.0.233 allows unauthenticated attackers to execute arbitrary OS commands via malicious tabby:// URL scheme links. When users click a crafted link containing tabby://run?command=..., Tabby spawns the specified command with full user privileges without any confirmation or sanitization. …
