The HTTPS protocol does not consider the role of the TCP congestion window in providing information about content length, which makes it easier for remote attackers to obtain cleartext data by leveraging a web-browser configuration in which third-party cookies are sent, aka a "HEIST" attack.

Exploit prediction (EPSS)

12.77% probability of exploitation in the next 30 days, higher than 96% of all scored CVEs.
