Tornado: Quadratic DoS via Crafted Multipart Parameters
Summary The parseparam function in Tornado's httputil.py is used to parse specific HTTP header values, such as those in multipart/form-data. This function uses an inefficient algorithm that repeatedly calls string.count within a nested loop while processing quoted semicolons e.g., param=";". As a...

GHSA-C98P-7WGM-6P64 Tornado: Quadratic DoS via Repeated Header Coalescing
Summary The HTTPHeaders.add method in Tornado accumulates values using string concatenation when the same header name is repeated. Due to Python string immutability, each concatenation copies the entire string, resulting in On² time complexity. Given Tornado's single event loop architecture, a...
