In May 2025, Aggh developed a security-focused feature for the gravitee-io/gravitee-api-management repository, enhancing Helm-based deployments by introducing EL whitelist support. This work involved updating gateway-configmap.yaml and gravitee.yml to allow administrators to specify approved Java classes and methods for Expression Language usage, thereby reducing the risk of arbitrary code execution. Aggh implemented configuration changes in Helm charts and wrote automated tests to ensure correct enforcement of the whitelist. Using YAML, Helm, and Kubernetes, the solution improved deployment safety and governance by providing auditable controls over EL expressions, demonstrating a thoughtful approach to security and configuration management in API environments.

May 2025 monthly summary focusing on key features delivered, major bugs fixed, impact, and technologies demonstrated. Concise highlights: Security-focused feature delivered for Gravitee API Management Helm deployments with EL whitelist support, increasing deployment safety by constraining EL expressions to approved Java classes/methods.
