CVE-2026-66276

A flaw was found in Apache Qpid Proton-J. An authenticated attacker can exploit this vulnerability by crafting a specially designed disposition frame with large or illegal ranges. This can cause excessive CPU usage due to naive range handling, leading to a denial of service DoS for the affected...

CVE-2026-67591

A flaw was found in Apache Qpid ProtonJ2. An authenticated attacker can exploit this vulnerability by exceeding the session flow control incoming window. This can lead to a denial of service DoS, making the system unavailable to legitimate users. Mitigation Ensure authenticated access to AMQP...

CVE-2026-66275

A flaw was found in Apache Qpid Proton-J. An authenticated attacker could exploit this by exceeding the session flow control incoming window. This action could lead to a denial of service DoS, making the system unavailable to legitimate users. Mitigation Ensure authenticated access to AMQP...

CVE-2026-66273
