CVE-2026-80104 eosphoros-ai CVE debrief

A critical vulnerability, CVE-2026-80104, exists in DB-GPT, allowing unauthenticated remote attackers to write arbitrary files and execute code on the server. The vulnerability arises from improper handling of file uploads, enabling attackers to bypass directory constraints and write to any path the server process can access. This can lead to arbitrary code execution when a malicious Python module is imported. The skill_upload endpoint in packages/dbgpt-app/src/dbgpt_app/openapi/api_v1/agentic_data_api.py does not constrain the destination path of uploaded files, allowing attackers to write to any path the server process can access. The endpoint is reachable without credentials due

Who should care

Defenders responsible for DB-GPT deployments should assess exposure and prioritize remediation. This vulnerability allows unauthenticated remote attackers to execute code on the server, posing a critical risk to affected systems.

Why it matters

CVE-2026-80104 is a critical vulnerability in DB-GPT that allows unauthenticated remote attackers to execute code on the server. Defenders should assess exposure, prioritize remediation, and implement compensating controls to mitigate the risk.

  • Unauthenticated remote code execution
  • Arbitrary file write access to server file system
  • Potential for lateral movement within the network
  • Need for immediate patching or mitigation

Technical summary

The DB-GPT application is vulnerable to an unauthenticated remote code execution attack due to improper handling of file uploads. The skill_upload endpoint in packages/dbgpt-app/src/dbgpt_app/openapi/api_v1/agentic_data_api.py does not constrain the destination path of uploaded files, allowing attackers to write to any path the server process can access. This can lead to arbitrary code execution when a malicious Python module is imported.

Defensive priority

High

Recommended defensive actions

  • Immediately upgrade to version 0.8.1 or later
  • Restrict access to the skill upload endpoint
  • Implement input validation and sanitization for file uploads
  • Monitor server logs for suspicious file write activity
  • Perform vulnerability scanning to identify exposed systems
  • Review access controls for the skill upload endpoint
  • Implement additional logging and monitoring for file upload activity
