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-2026-66275

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 ...

CVE-2026-66257

A pre-authentication attacker could leverage unbounded symbol value caching to cause resource exhaustion leading to denial of service. This issue affects Apache Qpid Proton-J: through 0.34.1. Users are recommended to upgrade to version 0.35.0, which fixes the issue...

CVE-2026-66273

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 Proton-J: through 0.34.1. Users are recommended to upgrade to version 0.35.0, which fixes the issue...

EUVD-2026-53093

It was not possible to govern the maximum number of transfer frames per incoming delivery, enabling an authenticated attacker to cause excessive resource usage and potential denial of service. This issue affects Apache Qpid Proton-J: through 0.34.1. Users are recommended to upgrade to version...

CVE-2026-66277

CVE-2026-66277 affects Apache Qpid Proton-J up to version 0.34.1. The issue is an inability to govern the maximum number of transfer frames per incoming delivery, allowing an authenticated attacker to cause excessive resource usage and potential denial of service. The recommended remediation is t...
