CVE-2026-27967 | Symlink Escape in Agent File Tools

Exp

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.

Base score Version Severity Vector Exploitability Impact Score source
7.1 3.1 HIGH
CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:N)
Service keeps running; no real outage angle.
