## Summary

Bastille, a FreeBSD jail management tool, is affected through its cp, rcp, and jcp subcommands. A user inside a jail can use symbolic links to make administrator-run copy operations read or overwrite files on the host system with root privileges, breaking out of jail isolation.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- BastilleBSD bastille: through 1.4.4

## Description

Bastille through 1.4.4 contains a symlink following vulnerability in the cp.sh, rcp.sh and jcp.sh subcommands that allows jailed users to escape jail isolation. Attackers inside a jail can plant symlinks pointing to host paths or other jail roots, so administrator-run copies overwrite or read host files with root privileges.
