CVE-2026-44466 Details
Description
Zed is a code editor. Prior to 0.229.0, Zed's terminal tool permission system can be bypassed via bash arithmetic expansion $((...)), allowing execution of arbitrary commands nested inside an allowlisted command like echo. This vulnerability is fixed in 0.229.0.
A vulnerability in Zed code editor versions prior to 0.229.0 allows users to bypass the terminal tool permission system. This is achieved through bash arithmetic expansion, which can be used to execute arbitrary commands nested within an allowlisted command, such as echo. The issue arises because the permission system's regex validation does not account for the arithmetic expansion syntax, enabling unauthorized command execution.
Users can update to Zed version 0.229.0 or later to address this vulnerability.
