Assigner: GitHub_M
Reserved: 11.05.2026 Published: 28.05.2026 Updated: 28.05.2026

GitButler is a modern Git-based version control interface for AI-powered workflows. Prior to 0.19.7, a emote code execution vulnerability exists in the Tauri-based GitButler desktop application. An attacker can inject a malicious link in a pull request body, which if clicked by the user allows for arbitrary script execution in the Tauri webview. Users that have not enabled forge integration are not at risk. This vulnerability is fixed in 0.19.7.
