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

A flaw was found in Apache Qpid Proton-J. A remote attacker, without needing to authenticate, could exploit a vulnerability in how the software handles type sizes and counts. This could lead to excessive memory allocation, causing the system to become unresponsive and resulting in a denial of...

CVE-2026-66257

A flaw was found in Apache Qpid Proton-J. A remote attacker, without needing to authenticate, could exploit an issue with unbounded symbol value caching. This could lead to resource exhaustion, where the system runs out of available resources, ultimately causing a denial of service DoS. A denial ...

Memory Allocation with Excessive Size Value

Overview org.apache.qpid:proton-j is a lightweight messaging library. Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value via improper handling of type size and count during the allocation process. An attacker can trigger excessive memory allocation by...
