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.
CVE-2026-27967
HIGHPre-NVD 7.17.1
EchelonGraph scoreLOW confidence
This high-severity CVE scores 7.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
