CVE-2026-40288 — AI Deep Analysis Summary

🚨 **Essence**: A Code Injection flaw in PraisonAI's workflow engine. 📉 **Consequences**: Attackers can execute arbitrary commands and code, leading to total system compromise.…

🛡️ **Root Cause**: **CWE-78** (OS Command Injection). The vulnerability lies in the **Workflow Engine** failing to sanitize or properly validate inputs from untrusted YAML configurations before execution.

👥 **Affected**: **PraisonAI** versions **< 4.5.139** and **praisonaiagents** versions **< 1.5.140**. Developed by **MervinPraison**. If you are using these low-code multi-agent frameworks, you are at risk.

💀 **Attacker Capabilities**: Full **Remote Code Execution (RCE)**. Hackers gain the ability to run any OS command on the host server.…

⚡ **Exploitation Threshold**: **LOW**. The CVSS vector shows **AV:N** (Network), **AC:L** (Low Complexity), **PR:N** (No Privileges Required), **UI:N** (No User Interaction).…

🔍 **Public Exploit**: Currently, the **PoCs list is empty** in the provided data. However, given the severity (CVSS 9.8) and nature (RCE), public exploits are likely emerging soon. Do not wait for a PoC to act.

🔎 **Self-Check**: Scan your environment for **PraisonAI** installations. Check version numbers against **4.5.139** and **1.5.140**.…

✅ **Official Fix**: **YES**. The vendor has issued a security advisory (GHSA-vc46-vw85-3wvm). The fix is available in **PraisonAI ≥ 4.5.139** and **praisonaiagents ≥ 1.5.140**. Update immediately.

🚧 **No Patch Workaround**: If you cannot update immediately, **disable the workflow engine** or restrict YAML input sources to strictly trusted/internal sources only.…

🔥 **Urgency**: **CRITICAL**. With a CVSS score of **9.8** (Critical) and no authentication required, this is a high-priority vulnerability. Patch immediately to prevent remote takeover of your AI infrastructure.
