{"id":"GHSA-c5hg-mr8r-f6jp","summary":"Hazelcast connection caching","details":"### Impact\nThe Connection handler in Hazelcast and Hazelcast Jet allows an unauthenticated, remote attacker to access and manipulate data in the cluster with another authenticated connection's identity.\nThe affected Hazelcast versions are through 3.12.12, 4.0.6, 4.1.9, 4.2.5, 5.0.3, and 5.1.2.\nThe affected Hazelcast Jet versions are through 4.5.3.\n\n### Patches\nHazelcast Jet (and Enterprise) 4.5.4.\nHazelcast IMDG (and Enterprise)3.12.13\nHazelcast IMDG (and Enterprise) 4.1.10\nHazelcast IMDG (and Enterprise) 4.2.6\nHazelcast Platform (and Enterprise) 5.1.3\n\n### Workarounds\nThere is no known workaround, but setups with TLS and mutual authentication enabled significantly lowers the exploitation risk.\n\n###
