Mar 1, 2026Month 2026-03 Summary for google/osv-scalibr: Focused on data correctness, migration readiness, and performance improvements. Implemented a protobuf-based Location data model overhaul with structured fields and dedicated structs for package and secret locations, and deprecated legacy fields to enable a clean plugin migration path. This lays groundwork for reliable cross-repo location handling and smoother plugin adoption. Improved test reliability and CI speed by removing unnecessary sleeps in context cancellation tests. Upgraded SCALIBR scanner from 0.4.4 to 0.4.5 to take advantage of newer enhancements and fixes. Together, these changes reduce migration risk, shorten release cycles, and enhance scan accuracy, delivering measurable business value through faster plugin integration, more predictable deployments, and improved security coverage.

Nov 1, 2025November 2025 focused on boosting configurability, safety, and maintainability of the osv-scalibr workflow. Key capabilities were extended with a Global Plugin Configuration System (with per-plugin CLI overrides), safety hardening via global file size limits for extractors, and improved path handling for OS duplicate annotators using a scan-root mapping. The release also upgraded SCALIBR to 0.4.0 with longer buffers for the azuretoken detector, and a targeted codebase cleanup removed deprecated fields/enums and outdated extractors, reducing tech debt and lint issues. These changes collectively improve scanning flexibility, reliability, and efficiency, while enhancing detector coverage and developer productivity.

May 1, 2025May 2025 achievements for google/osv-scalibr: Delivered a centralized PURL generation library consolidating PURL creation for NPM, Hex, Java, Go, Windows, SPDX/CDX, DPKG, Homebrew, and filesystem/os extractors, enabling consistent, spec-compliant identifiers across ecosystems. Added chain_id to LayerDetails proto to support multi-chain contexts, enabling future multi-chain analyses. Introduced Annotator plugin type and relocated cachedir to support plugin-based extensibility. Standardized scanning workflow by centralizing ScanInput handling via scalibrfs.ScanRoot, propagated the current GitHub release version to scan results, and added a --version flag to SCALIBR. Refactored the Extractor API to remove ToPURL/Ecosystem usage in favor of Package.PURL(), and expanded extraction capabilities (FilesystemExtractors directory-based extraction; Windows extractors now declare Windows requirements). Implemented stability improvements including removing an unnecessary wrapper around baseimage.NewDefault and correcting Podman extractor's metadata field and deprecated import.
