CVE-2026-44338 is an authentication bypass in PraisonAI versions 2.5.6 through 4.6.33 that allows unauthenticated attackers to list your agent configurations and trigger arbitrary agent workflow execution. It was disclosed May 11, 2026 and was being actively exploited within 4 hours.

This guide walks through: checking your installed version, patching, verifying the fix, auditing network exposure, and reviewing logs for indicators of compromise.

Note: All commands in this guide are standard pip and system tools. For PraisonAI-specific configuration options and advanced deployment settings, always refer to the official PraisonAI documentation — don’t rely solely on this guide for edge-case deployment scenarios.

Step 1: Check Your Installed PraisonAI Version

pip show praisonai | grep Version

If the output shows any version between 2.5.6 and 4.6.33, you are vulnerable. Proceed immediately.

If you’re using a virtual environment, activate it first:

source /path/to/your/venv/bin/activate
pip show praisonai | grep Version

In a Docker container:

docker exec -it <container-name> pip show praisonai | grep Version

Step 2: Patch — Upgrade to 4.6.34 or Later

pip install --upgrade praisonai

If you’re using a requirements file, update the pinned version:

praisonai>=4.6.34

Then reinstall:

pip install -r requirements.txt

Verify the upgrade succeeded:

pip show praisonai | grep Version
# Should output: Version: 4.6.34 (or later)

Docker users: Rebuild your image with the updated requirements or base image tag. If you’re using praisonai as a base image, pull the updated tag and rebuild.

Step 3: Verify Port 8080 Is Not Exposed to Untrusted Networks

The vulnerability is in a Flask API server that binds to 0.0.0.0:8080 with authentication disabled. Even after patching, auditing your network exposure is good practice.

Check if port 8080 is currently listening:

ss -tlnp | grep 8080
# or
netstat -tlnp | grep 8080

If port 8080 appears in the output and PraisonAI is running, the Flask API server is active.

Check if port 8080 is reachable from outside your server:

On a Linux host with ufw:

sudo ufw status | grep 8080

If you see port 8080 with ALLOW status, restrict it:

sudo ufw deny 8080
sudo ufw reload

Cloud instances: Check your security group (AWS), firewall rules (GCP), or network security group (Azure) in the cloud console. Port 8080 should not be open to 0.0.0.0/0.

Docker: If you started your PraisonAI container with -p 8080:8080, this maps the port to your host. Remove that flag or add a firewall rule blocking external access to 8080.

Step 4: Review Logs for Indicators of Compromise

If you were running a vulnerable version with port 8080 accessible, review your logs for unauthorized access since May 11, 2026.

What to look for:

  • GET /agents requests — this lists your agent configurations
  • POST /chat requests from unrecognized source IPs — this triggers agent execution

PraisonAI’s default log location depends on your deployment. Common locations:

  • ~/.praison/logs/ (local installs)
  • The working directory where you started PraisonAI
  • Application container stdout/stderr logs

Search your access logs:

grep -E "(GET /agents|POST /chat)" /path/to/your/access.log

Filter for requests since May 11:

grep -E "(GET /agents|POST /chat)" /path/to/your/access.log | grep "2026-05-1[1-9]"

If you find unauthorized requests:

  • Treat any credentials, API keys, or sensitive data accessible to your agents as potentially compromised
  • Rotate affected credentials immediately
  • Review what actions were taken via the /chat endpoint — check agent execution logs for commands run
  • Consider your host as potentially compromised if the exploited workflow had access to sensitive system resources

Step 5: Post-Patch Validation

After upgrading and restricting network access:

  1. Restart PraisonAI cleanly
  2. Verify the version again: pip show praisonai | grep Version
  3. Confirm port 8080 behavior matches your expectations (either not listening, or only bound to localhost)
  4. Run a brief functional test to confirm your agent workflows still operate correctly after the upgrade

Summary Checklist

  • Check installed PraisonAI version — is it 2.5.6 through 4.6.33?
  • Upgrade to 4.6.34+: pip install --upgrade praisonai
  • Verify upgrade: pip show praisonai | grep Version
  • Check port 8080 exposure and restrict if needed
  • Review logs from May 11 onward for unauthorized /agents or /chat requests
  • Rotate credentials if unauthorized access found
  • Rebuild Docker images if containerized
