Uncontrolled Resource Consumption

Apache Qpid ProtonJ2 is vulnerable to Uncontrolled Resource Consumption. The vulnerability is due to the lack of a limit on the number of transfer frames per incoming delivery, which allows an authenticated attacker to cause excessive resource consumption and potentially trigger a denial-of-servi...

Resource Exhaustion

Apache Qpid ProtonJ2 is vulnerable to resource exhaustion. The vulnerability is due to unbounded symbol value caching, where symbol values are cached without size limits and a pre-authentication attacker can send crafted input to exhaust resources, leading to denial of service...

qpid-protonj2: Apache Qpid ProtonJ2: Denial of Service via unbounded type nesting

A flaw was found in Apache Qpid ProtonJ2. A remote attacker, without needing to authenticate, could exploit a vulnerability related to unbounded type nesting. This could lead to a StackOverflowError, causing the application to become unresponsive and resulting in a denial of service...

org.apache.qpid/protonj2: Apache Qpid ProtonJ2: Denial of Service via excessive memory allocation

A flaw was found in Apache Qpid ProtonJ2. A remote, unauthenticated attacker could exploit a vulnerability in the handling of type sizes and counts, leading to excessive memory allocation. This could result in a denial of service DoS, making the affected system unavailable to legitimate users...

CVE-2026-67590

A flaw was found in Apache Qpid ProtonJ2. A remote attacker, without needing to authenticate, could exploit a vulnerability related to unbounded type nesting. This could lead to a StackOverflowError, causing the application to become unresponsive and resulting in a denial of service...

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...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via unbounded caching in the symbol process. An attacker can exhaust system resources by sending specially crafted requests prior to authentication. Remediation Upgrade...

Memory Allocation with Excessive Size Value

Overview Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value via improper handling of type size and count during the pre-authentication process. An attacker can trigger excessive memory allocation by sending specially crafted input, potentially leading ...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to insufficient enforcement of limits on the number of transfer frames per incoming delivery. An attacker can exhaust system resources and disrupt service availability by sending ...

Uncontrolled Recursion

Overview Affected versions of this package are vulnerable to Uncontrolled Recursion through unbounded nesting of types in the process. An attacker can cause a stack overflow and disrupt service availability by sending specially crafted input prior to authentication. Remediation Upgrade...
