- To reduce exposure, ensure that the `browserslist` tool processes only trusted `browserslist-stats.json`, `opts.stats`, and CLI `--stats` data. Avoid using the tool with untrusted input sources in development or build environments. If `browserslist` is integrated into automated pipelines, validate all input data originates from trusted sources.
