description

praxis-proxy versions before 0.5.2 can consume excessive memory while processing HTTP/2 header compression data. A remote attacker may cause service disruption by sending requests to an HTTP/2-enabled listener; no authentication is indicated.

mitigation

Upgrade praxis-proxy to version 0.5.2 or later. Until upgrades are complete, restrict untrusted access to HTTP/2 listeners.

fixed in 0.5.2
