How to Fix CVE-2026-5463

To remediate this vulnerability, upgrade all affected Pymetasploit3 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

pymetasploit3 fixed: Latest secure release 
pip install pymetasploit3>=Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show pymetasploit3

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-5463, inspect your installed packages using pip:

pip show pymetasploit3

Analyze the terminal output to locate any version of Pymetasploit3 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The pip show pymetasploit3 command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection'), where the product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. In Pymetasploit3, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Command injection vulnerability in console.run_module_with_output() in pymetasploit3 through version 1.0.6 allows attackers to inject newline characters into module options such as RHOSTS. This breaks the intended command structure and causes the Metasploit console to execute additional unintended commands, potentially leading to arbitrary command execution and manipulation of Metasploit sessions.
