CVE-2026-44463 Details
Description
Zed is a code editor. Prior to 0.229.0, Zed's terminal tool permission system can be bypassed by prepending environment variable assignments to allowlisted commands, hijacking program behavior (e.g., PAGER) to execute arbitrary code. This vulnerability is fixed in 0.229.0.
A vulnerability in Zed code editor versions prior to 0.229.0 allows for bypassing the terminal tool permission system. This is achieved by prepending environment variable assignments to allowlisted commands, which can hijack program behavior (such as the PAGER variable) to execute arbitrary code. The issue arises because Zed's regex-based allowlist does not consider environment variable prefixes, enabling the execution of attacker-controlled programs via common CLI tools that respect user-defined environment variables.
Users should update to Zed version 0.229.0 or later, where this vulnerability has been fixed.
