Worked on the gleam-lang/gleam repository to address a security vulnerability in documentation path handling. Focused on backend development using Rust, the work involved implementing strict validation for documentation page paths and sources to ensure they remained within the project root and documentation output directory. This approach prevented unauthorized file access through documentation configurations, reducing the risk of exposing internal files and improving the reliability of the documentation build process. The solution leveraged path validation, input sanitization, and secure coding practices, demonstrating attention to traceability and robust security measures within the codebase. No new features were added during this period.
