Worked on backend development for the percona/everest repository, focusing on security improvements within the authentication flow. Addressed a bug by normalizing the OIDC issuer URL in the Content-Security-Policy connect-src directive, specifically removing any trailing slash before appending the well-known path. This adjustment reduced the risk of CSP misconfigurations and ensured consistent security header behavior across different environments. The solution improved the robustness and reliability of OIDC authentication by eliminating edge cases that could lead to policy violations or denied requests. Utilized Go for implementation, applying backend development and security expertise to enhance the project’s overall security posture.
