Overview
CVE-2024-55950 is a known-severity vulnerability. It was published on December 26, 2024.
Technical description
Tabby (formerly Terminus) is a highly configurable terminal emulator. Prior to 1.0.216, Tabby terminal emulator contains overly permissive entitlements that are unnecessary for its core functionality and plugin system, creating potential security vulnerabilities. The application currently holds powerful permissions including camera, microphone access, and the ability to access personal folders (Downloads, Documents, etc.) through Apple Events, while also maintaining dangerous entitlements that enable code injection. The concerning entitlements are com.apple.security.cs.allow-dyld-environment-variables and com.apple.security.cs.disable-library-validation. Since Tabby's plugins and themes are NodeJS-based without native libraries or frameworks, and no environment variables are used in the codebase, it is recommended to review and remove at least one of the entitlements (com.apple.security.cs.disable-library-validation or com.apple.security.cs.allow-dyld-environment-variables) to prevent
