## How to fix

- Fixed in 1.6.20, 1.7.5

## Technical details

The squirrelmail_usercopy plugin constructs file paths from the login name without validating for path separators, allowing an attacker to inject directory traversal sequences (e.g., a login name containing slashes) to read files outside squirrelmail_data_dir. The vulnerability requires the file-based backend configuration and the ability to provide a malicious login name. The fix rejects login names containing forward slashes.
