How to Fix CVE-2025-64171

To remediate this vulnerability, upgrade all affected MARIN3R 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/3scale-sre/marin3r fixed: 0.13.4 
Upgrade github.com/3scale-sre/marin3r to 0.13.4
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/3scale-sre/marin3r

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-64171, inspect your project dependencies for MARIN3R:

inspect dependencies for github.com/3scale-sre/marin3r

Analyze the terminal output to locate any version of MARIN3R in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.13.4), 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-862: Missing Authorization, where the product does not perform an authorization check when an actor attempts to access a resource or perform an action. In MARIN3R, 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

## Summary Cross-namespace Secret access vulnerability in DiscoveryServiceCertificate allows users to bypass RBAC and access Secrets in unauthorized namespaces. ## Affected Versions All versions prior to v0.13.4 ## Patched Versions v0.13.4 and later ## Impact Users with permission to create DiscoveryServiceCertificate resources in one namespace can indirectly read Secrets from other namespaces, completely bypassing Kubernetes RBAC security boundaries. ## Workarounds Restrict DiscoveryServiceCertificate create permissions to cluster administrators only until patched version is deployed. ## Credit Thanks to @debuggerchen for the responsible disclosure.
