Last modified

CVE-2024-7592 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. There is a LOW severity vulnerability affecting CPython, specifically the 'http.cookies' standard library module. When parsing cookies that contained backslashes for quoted characters in the cookie value, the parser would use an algorithm with quadratic complexity, resulting in excess CPU resources being used while parsing the value.. EPSS estimates a 2.30% chance of exploitation in the next 30 days.
