The HTTP/2 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.
