GHSA-93p3-5r25-4p75

GHSA-93p3-5r25-4p75 PUBLISHED CVSS 7.5 HIGH

Record from GitHub Advisory Database · Published May 24, 2022

Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU.
