  "account": "In May 2026, the reporter began their Google Summer of Code (GSoC) project with OWASP OWTF, initially aiming to create a runtime sandbox for community plugins. However, after two weeks, their mentor convinced them to abandon the sandbox idea in favor of building a review queue system. This post explores the journey of this project and the final deliverables.\n\nThe OWTF framework, a security testing tool, had a static plugin catalogue until this summer, with no option for community plugins to be added. The reporter's goal was to allow authenticated users to upload Python plugins through the web interface. Uploaded plugins would be validated at upload time, placed in a pending queue, and eventually mirrored into OWTF's standard plugin table once approved.\n\nThe original proposal focused on sandboxing community plugins within OWTF, but after discussions with their mentor, the trust model evolved. Instead of relying on sandboxing, the new approach required admin source code review as the primary security boundary. This change led to two key modifications: a static AST validator and serializer discipline.\n\nThe static AST validator rejected code with potential security vulnerabilities during the upload process. It blocked imports of sensitive modules and functions, such as os, sys, subprocess, socket, eval, exec, and file writes. The validator also tracked aliasing of imports to catch dangerous code that might bypass simple blocking rules.\n\nAdditionally, serializer discipline restricted the server from passing potentially sensitive data, like file paths, through the API. This ensured that community plugins adhered to OWTF's security boundaries.\n\nThe reporter submitted six pull requests, each addressing a specific aspect of the marketplace implementation. These PRs included a data model, AST validator, admin role, JWT decorators, REST endpoints, runner integration, and a trust model document. The validator emerged as the most interesting component, as it played a critical role in preventing malicious code from entering the system.\n\nHowever, the reporter encountered two significant challenges during the development process. First, SQLite's lack of foreign key enforcement led to a bug that only appeared in production PostgreSQL, requiring the insertion of a real mirror row into the standard plugins table. Second, a large single PR containing all the changes proved difficult to review and merge, prompting the reporter to split the work into six separate PRs. This change improved reviews, provided sharper feedback, and allowed each PR to progress independently.\n\nIn conclusion, the reporter learned valuable lessons during this GSoC project. They discovered the importance of enforcing foreign key constraints and splitting large pull requests to facilitate better code review. The final deliverables, including the six PRs, the trust model document, and the AST validator, contributed to enhancing OWTF's security and community plugin ecosystem.",
