Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
PraisonAI is a multi-agent teams system. Prior to version 4.6.40 of PraisonAI, corresponding to version 1.6.40 of praisonaiagents, `execute_code()` in `praisonaiagents/tools/python_tools.py` (v1.6.37, subprocess sandbox mode) can be fully bypassed using `print.__self__` to retrieve the real Python `builtins` module, from which `__import__` can be extracted via `vars()` and runtime string construction. This achieves arbitrary OS command execution on the host, completely defeating the sandbox. This is a novel bypass that survives all patches for CVE-2026-39888 (frame traversal), CVE-2026-34938 (str subclass), and CVE-2026-40158 (`type.__getattribute__` trampoline). PraisonAI version 4.6.40 and praisonaiagents version 1.6.40 contain an updated fix.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · low confidence
Developing — this CVE was published recently and its authoritative NVD entry is still being established, so we're holding a technical summary until the source data settles rather than publish something unreliable. Re-checking after 2026-08-04.

Recommended fix High confidence

Upgrade to PraisonAI version 4.6.40 or higher, or praisonaiagents version 1.6.40 or higher

  1. 1. Identify the currently installed version of PraisonAI or praisonaiagents by checking your environment (e.g., `pip show praisonaiagents` or `pip show praisonai`)
  2. 2. If the installed version is prior to 1.6.40 (for praisonaiagents) or prior to 4.6.40 (for PraisonAI), upgrade using: `pip install --upgrade praisonaiagents` or `pip install --upgrade praisonai`
  3. 3. Verify the upgrade was successful by checking the new version: `pip show praisonaiagents` or `pip show praisonai`
  4. 4. Confirm the version number is 1.6.40 or higher for praisonaiagents, or 4.6.40 or higher for PraisonAI
  5. 5. Test that the `execute_code()` function still works as expected in your application
Caveat Review release notes for any API changes between your current version and 4.6.40/1.6.40 to ensure compatibility with existing code
