CVE-2026-119704 Details
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.
A symlink following vulnerability has been identified in Bastille versions through 1.4.4. This issue resides within the 'cp.sh', 'rcp.sh', and 'jcp.sh' subcommands, allowing jailed users to escape their confinement. Attackers can create symlinks that point to host files or other jail roots. When an administrator executes file copy commands, these symlinks can be followed, leading to unauthorized overwriting or reading of host files with root privileges.
Users can upgrade to Bastille version 1.4.4 or later, where this vulnerability has been addressed.
