Versions prior to 0.0.26 have a denial of service vulnerability when parsing crafted \u0060multipart/form-data\u0060 requests with large preamble or epilogue sections. Upgrade to version 0.0.26 or later, which skips ahead to the next boundary candidate when processing leading CR/LF data and immediately discards epilogue data after the closing boundary.",
