CVE-2026-62176 · Severity: critical · CVSS 9.1 · Published 2026-10-07

PraisonAI is a Python framework for building AI agent applications. The deploy module generates and executes Python server code by unsafely inserting user-supplied parameters into f-strings without validation. An attacker who controls the agents_file parameter—through CLI arguments, configuration files, or CI/CD pipelines—can break out of the string context and inject arbitrary Python code that executes with the privileges of the deploy process.

## Quick answers

**Is CVE-2026-62176 exploited in the wild?** No. Junglewise Threat Intelligence has no report of CVE-2026-62176 being exploited in the wild.

**How severe is CVE-2026-62176?** Critical severity, with a CVSS score of 9.1, published 7 October 2026.

**Which products and versions are affected?** MervinPraison PraisonAI <= 4.6.77; praisonai (PyPI) <= 4.6.77.

**Is there a fix for CVE-2026-62176?** Yes: fixed in 4.6.78. Junglewise finds every place you run it, drafts the upgrade and applies it once you approve.

**How is CVE-2026-62176 attacked?** It is attacked over the network, in a software library.

**Am I affected by CVE-2026-62176?** Check whether you run MervinPraison PraisonAI or praisonai (PyPI) 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

- Fixed in 4.6.78

## Technical details

The vulnerability is a code injection flaw (CWE-94) in the deploy/api.py and deploy/docker.py modules. The agents_file parameter is directly interpolated into an f-string template without sanitization, and the generated code is executed via subprocess.Popen(). An attacker can inject strings like `"); import os; os.system("id"); #` to break out of the string literal and inject arbitrary Python statements. The attack requires no user interaction and network access is possible if agents_file originates from an external API or config management system.

## Affected products
