# AgenticSeek: debug mode on all interfaces lets attackers run server code

AgenticSeek's LLM server runs Flask with debug mode hardcoded and binds to every network interface. An attacker who reaches the port and derives the Werkzeug debugger PIN can run Python and operating system commands with the llm_server's privileges.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

Check whether llm_server/app.py in your AgenticSeek checkout sets debug=True and binds to 0.0.0.0, and whether port 5000 or the llm_server port is reachable from outside the host.

## Fix

Upgrade AgenticSeek to commit 409840c or later. Until then, block the llm_server port from untrusted networks.

## Timeline

- 2026-10-23T21:57:32+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-115727
- 2026-10-25T12:38:51+00:00 epss https://api.first.org/data/v1/epss?cve=CVE-2026-115727

## From the sources

AgenticSeek before commit 409840c contains a remote code execution vulnerability because llm_server/app.py hardcodes Flask debug mode while binding to all interfaces. Attackers who reach the server port and obtain the derivable Werkzeug debugger PIN can execute Python code and operating system commands with llm_server privileges.
