Zed, a code editor, has a Zip Slip (Path Traversal) vulnerability exists in its extension archive extraction functionality prior to version 0.224.4. The extract_zip() function in crates/util/src/archive.rs fails to validate ZIP entry filenames for path traversal sequences (e.g., ../). This allows a malicious extension to write files outside its designated sandbox directory by downloading and extracting a crafted ZIP archive. Version 0.224.4 fixes the issue.
