org.apache.activemq/activemq: org.apache.activemq/activemq-all: org.apache.activemq/activemq-stomp: Apache ActiveMQ: Denial of Service via improper input validation in STOMP connector

A flaw was found in Apache ActiveMQ. A remote, unauthenticated attacker can exploit an improper input validation vulnerability by sending a specially crafted message with a negative content-length to an exposed STOMP connector. This can lead to a denial of service DoS condition, either by consumi...

activemq-stomp: Apache ActiveMQ, Apache ActiveMQ All, Apache ActiveMQ Stomp: Unbounded header buffer in STOMP NIO codec

An unbounded memory allocation flaw was found in the STOMP NIO codec of Apache ActiveMQ Classic. An unauthenticated remote client can open a STOMP NIO connection and send an unterminated header, causing the broker to buffer input without limit and potentially exhaust the JVM heap, resulting in a...

Integer Overflow or Wraparound

Overview Affected versions of this package are vulnerable to Integer Overflow or Wraparound in StompSubframeDecoder.java, where getContentLength accepts an unbounded long while alreadyReadChunkSize is an int, and the truncating cast at line 149 wraps a value above Integer.MAXVALUE to a negative...

CVE-2026-26449

A flaw was found in Stomper. A remote attacker can send a specially crafted message, specifically a SEND frame missing the destination header field, to the server. This action triggers a null pointer dereference, which is an attempt to access memory that does not exist, causing the server process...

CVE-2026-26448

A flaw was found in Stomper. A remote attacker can trigger a use-after-free vulnerability by sending multiple CONNECT frames on the same TCP connection, followed by SEND frames to a previously subscribed destination. This can cause the broker to dereference a freed memory region, leading to a hea...

CVE-2026-26445

A flaw was found in stomper. A remote attacker can exploit this by sending partial STOMP Streaming Text Oriented Messaging Protocol frames. This action can cause the broker's sockets to enter a permanent half-read state. Consequently, the broker stops processing new messages, leading to a Denial ...

Linux Distros Unpatched Vulnerability : CVE-2026-26445

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - stomper 5e2741e is vulnerable to Denial of Service. A malicious client can send partial STOMP frames and keep the TCP connections open, which, combined with the...

CVE-2026-26445

stomper 5e2741e is vulnerable to Denial of Service. A malicious client can send partial STOMP frames and keep the TCP connections open, which, combined with the broker s use of edge-triggered epoll EPOLLET and MSGPEEK in recv, causes sockets to enter a permanent half-read state. When enough such...

CVE-2026-26445

The stomper 5e2741e message broker is vulnerable to a Denial of Service (DoS) attack. A remote attacker can exploit this by sending partial STOMP (Streaming Text Oriented Messaging Protocol) frames while maintaining open TCP connections. Due to the broker's use of edge-triggered epoll (EPOLLET) a...

Improper Input Validation

Apache ActiveMQ is vulnerable to an Improper Input Validation vulnerability. The vulnerability is due to improper validation of negative content-length values in STOMP requests, which allows a remote unauthenticated attacker with access to an exposed STOMP connector to send malicious body data an...

Denial Of Service (DoS)

Apache ActiveMQ is vulnerable to a Memory Allocation with Excessive Size Value vulnerability. The vulnerability is due to improper handling of non-terminating STOMP header bytes, which allows an unauthenticated attacker to send an excessive amount of header data over a STOMP NIO connection, causi...
