Technical details
The vulnerability is a reliance on untrusted input in a security decision, affecting the WorkspaceDirsService component in the .kimi-code/local.toml configuration file. An attacker with local access can manipulate the additional_dir argument to influence how the application handles workspace directories. The fix in version 2.1.0 includes rejection of additional directories that resolve to the home directory or filesystem root, blocking symlink-based attacks to escape the working directory.
