Description
Zed, a code editor, has an aribtrary code execution vulnerability in versions prior to 0.218.2-pre. The Zed IDE loads Language Server Protocol (LSP) configurations from the `settings.json` file located within a project’s `.zed` subdirectory. A malicious LSP configuration can contain arbitrary shell commands that run on the host system with the privileges of the user running the IDE. This can be triggered when a user opens project file for which there is an LSP entry. A concerted effort by an attacker to seed a project settings file (`./zed/settings.json`) with malicious language server configurations could result in arbitrary code execution with the user's privileges if the user opens the project in Zed without reviewing the contents. Version 0.218.2-pre fixes the issue by implementing worktree trust mechanism. As a workaround, users should carefully review the contents of project settings files (`./zed/settings.json`) before opening new projects in Zed.
