Apache Qpid Broker-J: Type size/count handling can lead to excessive allocation pre-authentication in the AMQP 0-8/0-9/0-9-1 decoder

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

A pre-authentication attacker could leverage type size/count handling to cause excessive allocation leading to potential denial of service. This issue affects Apache Qpid Broker-J: through 10.1.0. Users are recommended to upgrade to version 10.1.1, which fixes the issue.
