How to Fix CVE-2026-10692

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

code-index-mcp fixed: 2.14.1 
pip install code-index-mcp>=2.14.1
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 code-index-mcp

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-10692, inspect your installed packages using pip:

pip show code-index-mcp

Analyze the terminal output to locate any version of Code index mcp in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.14.1), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Code index mcp, 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 weakness has been identified in johnhuang316 code-index-mcp up to 2.14.0. Affected is the function is_safe_regex_pattern of the component search_code_advanced. Executing a manipulation of the argument regex can lead to inefficient regular expression complexity. It is possible to launch the attack remotely. The exploit has been made available to the public and could be used for attacks. Upgrading to version 2.14.1 is able to address this issue. This patch is called 25bc02fac74051ddae15ce79e952f00211b1ea6b. Upgrading the affected component is recommended.
