  • Published2026-10-29
  • WeaknessCWE-22

Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

DB-GPT v0.7.5 and 0.8.0 contains directory traversal in use_example_file (packages/dbgpt-app/src/dbgpt_app/openapi/api_v1/examples_api.py:129). A remote attacker can use the validated exploitation path to write files outside the intended workspace or storage boundary.
