Regular Expression Denial Of Service (ReDoS)

websocket-extensions is vulnerable to regular expression denial of service ReDoS. The vulnerability exists in the regular expression used to parse quotes, allowing an unclosed string parameter value, of a repeating two-byte sequence of a backslash and another character, to parse in quadratic time...

Regular Expression Denial Of Service (ReDoS)

websocket-extensions is vulnerable to regular expression denial of service ReDoS. A regex backtracking is introduced due to the way the parser processes the Sec-WebSocket-Extensions header, using up quadratic time in a single-threaded server when an unclosed string parameter with repeating two-by...

Medium: python

Issue Overview: http.cookiejar.DefaultPolicy.domainreturnok in Lib/http/cookiejar.py in Python before 3.7.3 does not correctly validate the domain: it can be tricked into sending existing cookies to the wrong server. An attacker may abuse this flaw by using a server with a hostname that has anoth...
