PraisonAI: [Path Traversal] agent tools escape the configured workspace via symlinks

Published Aug 25, 2026 CVSS 3.1 · 7.1 High EPSS < 1% KEV · Not listed
Description
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.
