CVE-2026-40287 · Severity: high · CVSS 8.4 · Published 2026-04-14

PraisonAI is an AI agent framework used to automate tasks and workflows. A security vulnerability allows the software to automatically execute a specific Python file if it is present in the folder where the application is started. If an attacker can place a malicious file in that location, they can gain full control over the host system and access sensitive data.

Technologies: [Praisonai](https://junglewise.ai/threats/technologies/praisonai), [Praisonaiagents](https://junglewise.ai/threats/technologies/praisonaiagents), [praisonai (PyPI)](https://junglewise.ai/threats/technologies/pypi-praisonai), [praisonaiagents (PyPI)](https://junglewise.ai/threats/technologies/pypi-praisonaiagents).

**Am I affected by CVE-2026-40287?** Check whether you run Praisonai, Praisonaiagents, praisonai (PyPI) or one of the others listed at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## How to fix

- praisonai (PyPI): upgrade to 4.5.139 or later

  ```sh
  pip install "praisonai>=4.5.139"
  ```

- praisonaiagents (PyPI): upgrade to 1.5.140 or later

  ```sh
  pip install "praisonaiagents>=1.5.140"
  ```


## Technical details

PraisonAI and praisonaiagents are vulnerable to arbitrary code execution via an untrusted search path (CWE-426) and code injection (CWE-94). The application automatically calls import_tools_from_file() and _load_local_tools() upon startup, which attempts to import a file named tools.py from the current working directory (./tools.py). An attacker with the ability to place a file in the process's working directory can achieve full code execution in the context of the PraisonAI process. This affects CLI tool-loading paths and workflow execution. The issue is fixed in PraisonAI version 4.5.139 and praisonaiagents version 1.5.140.

## Affected products

- MervinPraison PraisonAI <= 4.5.138
- MervinPraison praisonaiagents <= 1.5.139
