August 2025 monthly summary: In the Tsunami security ecosystem, delivered key security detection capabilities, improved build stability, and enhanced automation that directly drive business value and developer productivity across two repositories (google/tsunami-security-scanner-plugins and google/osv-scalibr). Key features delivered: - Apache Flink UI detector: new detector to identify exposed Apache Flink UIs vulnerable to unauthenticated job submission, with tests and plugin build configurations. - Dependency and build system improvements: consolidated stability and dependency management across plugins, including decoupling templated plugin builds from core Gradle versions (templated plugins now use the git-stable branch), aligning all Tsunami dependencies to a single version, and introducing (then rolling back) SHA-512 verification due to non-recursive computation issues. - Automation workflows for PRP and issue management: GitHub Actions automation to streamline PRP contributor journeys and improve issue handling (assignment, commenting, and status updates). - Bug fix: mock HTTP server initialization corrected to occur after detectors, ensuring injections and substitutions happen as intended. Major bugs fixed: - Mock HTTP server initialization race with detectors resolved to ensure proper injections. - OSV-Scalibr workflow robustness improvements to ensure welcome messages post reliably even if author assignment fails, with continue-on-error on the assignment step. Overall impact and accomplishments: - Strengthened security posture by detecting exposed Flink UIs earlier in CI pipelines. - Reduced build fragility and improved dependency governance across Tsunami repos, enabling faster release cycles. - Enhanced contributor onboarding and triage efficiency through automated PRP and issue-management workflows. - Improved reliability of test and deployment tooling, lowering risk of misconfigurations during plugin builds. Technologies/skills demonstrated: - GitHub Actions automation, Gradle and dependency management, test strategy, and plugin development. - Security-focused verification (SHA-512) and version alignment across multiple repositories. - Issue/PR lifecycle automation and CI workflow orchestration.
