During February 2025, Sam Khoury focused on security hardening for container libraries, specifically addressing a critical vulnerability in the go-jose dependency. Working across the containers/container-libs and containers/image repositories, Sam upgraded go-jose from v4.0.4 to v4.0.5 to mitigate CVE-2025-27144, ensuring both go.mod and go.sum files reflected the patched version. Using Go and leveraging skills in dependency management and security patching, Sam validated all commits and maintained build integrity throughout the process. This work reduced vulnerability exposure and aligned security standards across repositories, demonstrating a methodical approach to supply chain security and cross-repo collaboration within Go-based projects.
