CVE-2026-44466: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in zed-industries zed
Zed, a code editor, contains an OS command injection vulnerability (CVE-2026-44466) in versions prior to 0.229.0. The issue arises because the terminal tool permission system can be bypassed using bash arithmetic expansion $((... )), allowing execution of arbitrary commands nested inside an allowlisted command such as echo. This vulnerability has a high severity with a CVSS score of 8.6. The vulnerability is fixed in version 0.229.0.
AI Analysis
Technical Summary
CVE-2026-44466 is an OS command injection vulnerability in the Zed code editor before version 0.229.0. The vulnerability occurs because the terminal tool permission system can be bypassed via bash arithmetic expansion syntax $((...)), which enables an attacker to execute arbitrary commands nested inside an otherwise allowlisted command like echo. This improper neutralization of special elements (CWE-78) allows privilege escalation and command execution. The vulnerability is resolved in Zed version 0.229.0.
Potential Impact
Successful exploitation allows an attacker to bypass terminal tool permission restrictions and execute arbitrary OS commands with the privileges of the user running Zed. This can lead to full compromise of the affected system, including confidentiality, integrity, and availability impacts as indicated by the CVSS vector (C:H/I:H/A:H).
Mitigation Recommendations
Upgrade Zed to version 0.229.0 or later, where this vulnerability is fixed. No other mitigation or workaround is indicated. Patch status is confirmed by the vendor stating the issue is fixed in 0.229.0.
