Extensionscan

Extensionscan is a term used to describe a conceptual framework and potential tool for evaluating software extensions across ecosystems such as web browsers, integrated development environments, and app stores. It is intended to assist developers, security researchers, and enterprises in assessing extensions for security, privacy, license compliance, and compatibility prior to deployment or approval.

The system aggregates data from official manifest files, store metadata, and, where available, the extension’s source code. It performs static analysis of declared permissions and capabilities, checks against known vulnerability databases, and can execute dynamic analysis in a sandbox to observe network activity, file system access, and cross-extension interactions. It may also conduct privacy impact assessments and verify license obligations.

Output from extensionscan typically includes a risk score or categorization, a detailed vulnerability report, flags for high-risk permissions, privacy concerns, and a license compliance status. Remediation guidance, upgrade recommendations, and exportable reports (human-readable and machine-readable) facilitate integration into procurement, governance, or CI/CD workflows.

Extensionscan can be deployed as an open-source reference implementation, a cloud-based service, or an integrated feature within store submission pipelines. It commonly covers major extension ecosystems such as browser extensions (Chrome, Firefox, Edge), and software IDE plugins, providing metadata validation, compatibility checks, and supply chain risk indicators.

Limitations include dependence on data availability, potential false positives, and the challenge of analyzing obfuscated or server-side code. Sandbox environments may not capture all real-world behaviors. As a concept, extensionscan underlines efforts to improve the security and governance of software extensions.
