Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A vulnerability has been found in Fosowl agenticSeek 0.1.0. Impacted is the function PyInterpreter.execute of the file sources/tools/PyInterpreter.py of the component query Endpoint. Such manipulation leads to code injection. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A code injection vulnerability exists in Fosowl agenticSeek 0.1.0 within the PyInterpreter.execute function in sources/tools/PyInterpreter.py, accessible via the query endpoint. The vulnerability allows remote attackers to inject and execute arbitrary code due to insufficient input validation or sanitization of user-supplied data passed to the Python interpreter execution logic.

MitigationImplement strict input validation and sanitization on all data flowing to the PyInterpreter.execute function. Consider using sandboxing, whitelist-based validation, or replacing dynamic code execution with safer alternatives such as pre-defined command libraries or parameterized operations.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify Fosowl AgenticSeek installation and version
    Check if Fosowl AgenticSeek 0.1.0 is installed in your environment by inspecting installed packages or the application metadata
    Affected if The installed version is exactly 0.1.0
  2. Locate the PyInterpreter.py file
    Search for the file sources/tools/PyInterpreter.py within the Fosowl AgenticSeek installation directory
    Affected if The file exists at sources/tools/PyInterpreter.py in the application root
  3. Inspect the execute function implementation
    Open PyInterpreter.py and examine the execute function for how it handles input parameters
    Affected if The execute function exists and appears to pass user input directly to code execution without visible sanitization
  4. Confirm query endpoint accessibility
    Check if the query endpoint is exposed and routes to the PyInterpreter module
    Affected if The query endpoint is accessible and references the PyInterpreter.execute function
  5. Test execute function reachability
    Review application routing configuration to verify the execute function can be invoked via the query endpoint
    Affected if The execute function can be reached through the query endpoint without authentication or additional constraints

Your environment is affected if you are running Fosowl AgenticSeek version 0.1.0 with the query endpoint exposed and the PyInterpreter.execute function accessible without proper input validation in place.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Implement strict input validation and sanitization on all data flowing to the PyInterpreter.execute function. Consider using sandboxing, whitelist-based validation, or replacing dynamic code execution with safer alternatives such as pre-defined command libraries or parameterized operations.
