How to Fix CVE-2026-11529

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

mysql-mcp-server fixed: 0.3.0 
pip install mysql-mcp-server>=0.3.0
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 mysql-mcp-server

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-11529, inspect your installed packages using pip:

pip show mysql-mcp-server

Analyze the terminal output to locate any version of Mysql mcp server in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.3.0), your application is affected.

Note: The pip show mysql-mcp-server command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), where the product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. In Mysql mcp server, 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

A vulnerability was determined in designcomputer mysql-mcp-server up to 0.2.2. The impacted element is the function read_resource of the file src/mysql_mcp_server/server.py of the component mysql URI Handler. This manipulation of the argument uri_str causes sql injection. Remote exploitation of the attack is possible. The exploit has been publicly disclosed and may be utilized. Upgrading to version 0.3.0 is sufficient to resolve this issue. Patch name: 080bef9a96d625ce0dfbde573a08b93497871981. Upgrading the affected component is advised.
