How to Fix CVE-2025-59361

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

github.com/chaos-mesh/chaos-mesh fixed: 2.7.3 
Upgrade github.com/chaos-mesh/chaos-mesh to 2.7.3
Verify Direct and Transitive Dependencies

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

inspect dependencies for github.com/chaos-mesh/chaos-mesh

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-59361, inspect your project dependencies for Github.com/chaos mesh/chaos mesh:

inspect dependencies for github.com/chaos-mesh/chaos-mesh

Analyze the terminal output to locate any version of Github.com/chaos mesh/chaos mesh in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.7.3), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In Github.com/chaos mesh/chaos mesh, 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

The cleanIptables mutation in Chaos Controller Manager is vulnerable to OS command injection. In conjunction with CVE-2025-59358, this allows unauthenticated in-cluster attackers to perform remote code execution across the cluster.
