Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
CrateDB (Maven io.crate:crate) versions before 5.7.2 allow clients to initiate TLS renegotiation on the TLS endpoint at port 4200. An attacker who can reach that port can repeatedly force renegotiation during a session, exhausting server CPU and disrupting service availability. Upgrade to version 5.7.2 or later; no workaround is listed.
