GHSA-RJ75-HQRM-R3GF PostCSS: Quadratic complexity in flat selector parsing allows CPU exhaustion
Impact . and are not word delimiters in the tokenizer, so a flat selector such as .a.a.a... reaches splitWord as a single word token carrying n class or id indexes. Three passes scanned those index arrays linearly for every index, making the parse On^2 in the number of indexes rather than in inpu...
tornado-python: Tornado: Denial of Service via large multipart bodies
A flaw was found in tornado-python. A remote attacker can exploit this vulnerability by sending a specially crafted, very large multipart body with numerous parts. Because the parsing of these large bodies occurs synchronously on the main thread, it can consume excessive resources, leading to a...

Denial Of Service (DoS)
Tornado is vulnerable to Denial of Service DoS. The vulnerability is due to synchronous parsing of multipart/form-data without limiting the number of parts, allowing attackers to send large requests with many parts that consume excessive CPU and block the main thread...
