CVSS 9.8 Β· Critical

Q1What is this vulnerability? (Essence + Consequences)

🚨 **Essence**: Mesop allows **unrestricted code injection** via the `/exec-py` endpoint.…

Q2Root Cause? (CWE/Flaw)

πŸ›‘οΈ **Root Cause**: **CWE-94** (Code Injection). <br>πŸ” **Flaw**: The `ai/testing` module's `/exec-py` endpoint **unconditionally executes** unverified Python code without any input validation or sanitization.

Q3Who is affected? (Versions/Components)

πŸ“¦ **Affected**: **Mesop** (by mesop-dev). <br>πŸ“… **Versions**: **1.2.2 and earlier**. <br>⚠️ **Component**: Specifically the `ai/testing` module endpoint.

Q4What can hackers do? (Privileges/Data)

πŸ‘‘ **Privileges**: Full **Remote Code Execution (RCE)**. <br>πŸ“‚ **Data Impact**: Attackers can access, modify, or delete any data accessible to the Python process.…

Q5Is exploitation threshold high? (Auth/Config)

πŸ”“ **Threshold**: **LOW**. <br>🚫 **Auth**: **No authentication required** (PR:N). <br>🌍 **Access**: Requires only **HTTP access** to the server. <br>🎯 **Complexity**: Low (AC:L).

Q6Is there a public Exp? (PoC/Wild Exploitation)

πŸ’£ **Public Exploit**: **YES**. <br>πŸ“œ **PoC**: Available via **Nuclei Templates** (projectdiscovery). <br>⚑ **Status**: Exploitation is straightforward using base64-encoded Python code injection.

Q7How to self-check? (Features/Scanning)

πŸ” **Self-Check**: Scan for the `/exec-py` endpoint in the `ai/testing` module. <br>πŸ“‘ **Tooling**: Use **Nuclei** with the specific CVE-2026-33057 template to detect vulnerable instances.…

Q8Is it fixed officially? (Patch/Mitigation)

πŸ› οΈ **Fixed**: **YES**. <br>πŸ“ **Patch**: Refer to the official GitHub commit `825f559` and the security advisory **GHSA-gjgx-rvqr-6w6v**. <br>βœ… **Action**: Upgrade to a version newer than 1.2.2 immediately.

Q9What if no patch? (Workaround)

🚧 **No Patch?**: **Block external access** to the `/exec-py` endpoint via firewall rules. <br>πŸ”’ **Mitigation**: Disable the `ai/testing` module if not strictly needed for development.…

Q10Is it urgent? (Priority Suggestion)

πŸ”₯ **Urgency**: **CRITICAL**. <br>πŸ“‰ **CVSS**: **9.8** (High). <br>⏱️ **Priority**: **Immediate Action Required**. <br>πŸš€ **Reason**: Unauthenticated RCE with public PoCs makes this a high-priority target for attackers.
