CVE-2026-55540

Summary

PraisonAI is a multi-agent teams system. Prior to praisonai 4.6.51, is_path_within_directory() uses os.path.abspath() rather than os.path.realpath() for the workspace boundary. A symlink inside workspace can point outside and still pass the check, allowing read_file and other code tools to access files outside the configured workspace. This issue is fixed in version 4.6.58.
