What is CVE-2026-27967?

CVE-2026-27967 is a high-severity path traversal vulnerability in zed-industries zed, published on 25 Feb 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

Official description

Zed, a code editor, has a symlink escape vulnerability in versions prior to 0.225.9 in Agent file tools (`read_file`, `edit_file`). It allows reading and writing files **outside the project directory** when a project contains symbolic links pointing to external paths. This bypasses the intended workspace boundary and privacy protections (`file_scan_exclusions`, `private_files`), potentially leaking sensitive user data to the LLM. Version 0.225.9 fixes the issue.

Weakness: CWE-59
