Yili Li developed and enhanced core vulnerability management features for the StackRox platform, focusing on the stackrox/stackrox and stackrox/scanner repositories. Over nine months, Yili delivered robust solutions for vulnerability data export, risk scoring, and scanner reliability, using Go and Python to implement API design, concurrency controls, and configuration management. Their work included refining FixedInVersion logic, integrating EPSS risk metrics, and stabilizing dependency management, which improved data accuracy and operational resilience. By addressing edge cases in vulnerability reporting and optimizing CI/CD pipelines, Yili ensured more reliable releases and streamlined security workflows, demonstrating strong backend engineering and DevOps expertise throughout.

Month: 2025-10 — Delivered a targeted feature to establish a stable startup baseline for the scanner service within stackrox/scanner. This work focuses on correctness and predictability of defaults at initialization, enabling smoother deployments and reducing configuration drift. Key outcomes include a concrete feature delivery on baseline initialization using genesis_manifests.json, traceable to a single commit, and improved deployment reliability across environments.

July 2025: Delivered a critical bug fix in the scanner updater to support version-aware exports for scanner bundles. Implemented conditional application of the --split flag for v1 bundles, ensuring correct export behavior across versions. This work stabilizes exports, reduces deployment risk, and aligns with versioned feature expectations. Key change tracked in commit 3ae82dad574adaa65f38fa383910732f272e8344 and associated PR (#15887).

May 2025 — StackRox (stackrox/stackrox) highlights: two core deliverables focused on vulnerability data accuracy and scanner resilience, driving faster remediation and more stable operations. Key features delivered - Vulnerability FixedInVersion Accuracy Enhancement: improved vulnerability data precision by correcting FixedInVersion handling; updated lastAffected to fixed for three Tomcat embed CVEs and refined the FixedInVersion logic to ignore lastAffected when determining the fixed version. Commits: 961e7ff97019cca0b313077094d79f1abd4469e4; 5765d3c6ae4b3f3de5bba3e796042c37734a2458. - Increase Bundle Export Timeout and Update Dependencies: extended bundle export timeout to 6 hours; updated OpenTelemetry dependencies; temporarily forked quay.io/claircore to address a Vex update and resolve dependency conflicts. Commit: 325036c67b0e1eb4799645f93ac67d50e99b823f. Major bugs fixed - FixedInVersion handling edge cases causing misreporting of fixed versions for CVEs (three Tomcat embed CVEs); updated logic to ignore lastAffected when determining fixed version, improving accuracy of vulnerability data (ROX-25598, ROX-29284). Overall impact and accomplishments - Improved vulnerability reporting accuracy, enabling faster and more reliable remediation decisions. - Increased scanner resilience and throughput, reducing timeouts and operational overhead during exports. - Demonstrated effective patching of external components and dependency management (OpenTelemetry, Claircore forks). Technologies/skills demonstrated - CVE data modeling and FixedInVersion logic, Tomcat CVE handling - OpenTelemetry dependency management and observability enhancements - Timeout tuning and resilience in scanner export pipelines - Patch management and forking external dependencies (claircore)

February 2025 (stackrox/stackrox): Key contributions focused on strengthening vulnerability risk scoring and data reliability. Delivered EPSS Score Enrichment in Vulnerability Reports, enriching vulnerability data with probability and percentile scores for better risk prioritization. Updated the vulnerabilities data source URL to a cluster-internal endpoint, replacing a hardcoded Google Cloud Storage path to ensure the scanner uses a stable, internal data source. These changes improve risk-informed decision-making and operational resilience for security operations.
