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 was found in louisho5 picobot up to 0.2.0. This issue affects the function ExecTool.Execute of the file internal/agent/tools/exec.go of the component exec Tool. The manipulation results in os command injection. The attack requires a local approach. The exploit has been made public and could be used. The project was informed of the problem early through an issue report but has not responded yet.

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 · moderate confidence

OS command injection vulnerability in picobot's ExecTool.Execute function in internal/agent/tools/exec.go. User-supplied input is passed unsafely to OS command execution, allowing local attackers to execute arbitrary commands.

MitigationImplement strict input validation and sanitization, or replace shell command execution with safer alternatives that avoid shell interpretation (e.g., exec.Command with separate arguments rather than shell string concatenation).

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. Confirm picobot installation
    Locate the picobot binary or source code in your environment. Check for the presence of internal/agent/tools/exec.go file in the project directory.
    Affected if picobot is installed and the source file internal/agent/tools/exec.go exists
  2. Inspect the ExecTool.Execute function
    Open internal/agent/tools/exec.go and locate the Execute function definition. Examine how it processes input parameters.
    Affected if The Execute function exists and accepts user-supplied input parameters
  3. Identify command execution method
    Search within exec.go for patterns indicating OS command execution: look for calls to exec.Command, os/exec, shell execution (bash, sh, cmd.exe), or similar. Check if commands are constructed by concatenating strings vs using separate argument arrays.
    Affected if The code uses shell command execution (e.g., shell=True, string concatenation with user input, or direct shell invocation)
  4. Verify unsafe input handling
    Trace how user input flows from function parameters to the command execution. Look for direct string interpolation, formatting, or concatenation of user data into command strings without sanitization.
    Affected if User-supplied input is directly concatenated or interpolated into shell commands without validation or use of safe argument separation
  5. Check application attack surface
    Determine if the ExecTool is exposed to untrusted input. Check if there are API endpoints, CLI interfaces, or other entry points that pass user data to this Execute function.
    Affected if The Execute function can be triggered with user-controlled input from external sources

If picobot is installed with internal/agent/tools/exec.go containing ExecTool.Execute that passes user input directly to shell command execution without sanitization, the environment is vulnerable to CVE-2026-15669.
