Key points
- CVE-2026-77932 affects DB-GPT versions up to and including 0.8.2.
- The vulnerability allows unauthenticated remote code execution with root privileges.
- Attackers can exploit the /api/v1/chat/react-agent endpoint to run arbitrary Python or bash.
Security teams using eosphoros-ai DB-GPT must address a critical flaw that grants unauthenticated attackers full control over webserver containers. The vulnerability, identified as CVE-2026-77932, allows anyone to execute arbitrary code as the root user without providing credentials. This exposure puts the entire container environment at risk, including any bundled databases that rely on default access settings.
The issue stems from how the application handles user authentication at a specific API endpoint. According to the National Vulnerability Database, the /api/v1/chat/react-agent path uses a mock function called get_user_from_headers. This function incorrectly assigns the admin role to every caller, regardless of their actual identity. Consequently, the system treats unauthenticated requests as if they came from a privileged administrator.
Technical Mechanics of the Exploit
An attacker can send prompts to the vulnerable endpoint that trigger the ReAct agent’s built-in tools. These tools include an unsandboxed code_interpreter and a shell_interpreter. Because the caller is granted admin rights, these interpreters run with root privileges inside the webserver container. This allows the execution of arbitrary Python scripts or bash commands. The lack of sandboxing means the code has direct access to the host container’s filesystem and processes.
Scope of Affected Systems
The vulnerability impacts all versions of eosphoros-ai DB-GPT up to 0.8.2. Any deployment running these versions is exposed to unauthenticated remote code execution. The risk is particularly high for instances exposed to the internet or internal networks where untrusted users can reach the API. The flaw also enables access to bundled databases using default credentials, further expanding the potential attack surface for data exfiltration or manipulation.
Next steps
No patch or fix has been confirmed yet for this vulnerability. Teams should immediately identify all instances of DB-GPT running version 0.8.2 or earlier. If possible, isolate these systems from untrusted networks to prevent exploitation. Monitor for any official updates from eosphoros-ai regarding a patched version. Until a fix is available, restrict access to the /api/v1/chat/react-agent endpoint using network firewalls or web application firewalls.
Signals worth monitoring
Teams usually see unusual outbound traffic from containers that should not be communicating externally. Check logs for unexpected process executions, such as bash shells or Python interpreters, spawning from the webserver application. Look for authentication failures or anomalous requests to the react-agent endpoint from unknown IP addresses. Investigate any sudden changes in database connections or file permissions within the container. Alert on commands that attempt to access system binaries or network utilities, as these often indicate an attacker trying to establish persistence or pivot further into the environment.
What to do and how to stay safe: DB-GPT
- Restrict network access to the DB-GPT API endpoints, especially /api/v1/chat/react-agent, to trusted IPs only.
- Monitor container logs for unexpected process executions or command-line arguments that do not match normal application behavior.
- Disable or isolate the ReAct agent functionality if it is not critical to your current operations.
- Wait for the vendor to release an official update before re-exposing the service to broader networks.

Frequently asked questions
Which versions of DB-GPT are vulnerable to CVE-2026-77932?
All versions of eosphoros-ai DB-GPT up to and including 0.8.2 are affected by this vulnerability.
Does this vulnerability require authentication to exploit?
No, the vulnerability allows unauthenticated attackers to execute code because the endpoint grants admin roles to all callers.
What tools can an attacker use to exploit this flaw?
Attackers can use the ReAct agent's unsandboxed code_interpreter and shell_interpreter tools to run arbitrary Python or bash commands.
