PraisonAI: [Path Traversal] agent tools escape the configured workspace via symlinks
GitHub lists this reviewed advisory for PraisonAI. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.

### Summary PraisonAI's `praisonai.code` tool wrappers (exported as `CODE_TOOLS` for agents) expose a `workspace` setting that the module itself treats as a path-traversal **security boundary** — `read_file`, `write_file`, `apply_diff`, and `search_replace` explicitly call `is_path_within_directory()` and return `"… is outside the workspace"` on violations. That boundary is enforced **unsoundly and inconsistently**: 1. The containment helper uses `os.path.abspath()`, not `realpath()`/`Path.resolve()`. A symlink located **inside** the workspace whose target is **outside** has an `abspath()` that is still inside the workspace, so it passes the check while `open()` follows the link. This bypasses read, write, apply_diff, and search_replace (CWE-59). 2. `list_files()` resolves `path` against the workspace but **never** calls the containment helper at all — `../` and absolute paths escape directly (CWE-22). 3. `execute_command()` takes a `workspace` argument documented "for security validation" but performs **no** `cwd` containment check; `code_execute_command()` resolves a relative `cwd` against the workspace and also never validates it (and never even passes `workspace` to the low-l
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
