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...

CVE-2026-16308

IBM Enterprise Build of Quarkus 3.27.1 through 3.27.4.SP2, and 3.33.1 through 3.33.2.SP2 Quarkus REST could allow a remote attacker to cause a denial of service due to unbounded accumulation of multipart MIME part-header bytes...

EUVD-2026-46392

CImg Library is a C++ library for image processing. Prior to version 4.0.0 in loadanalyze, the headersize field is read as an unsigned int from the first 4 bytes of an Analyze/NIfTI file and passed directly to new unsigned charheadersize without being bounded against the actual file size. A value...

CVE-2026-54465 websocket-driver: Memory exhaustion in HTTP header parser

websocket-driver is a WebSocket protocol handler with pluggable I/O. Prior to 0.8.1, when websocket-driver is used to implement a WebSocket server on top of a TCP server using WebSocket::Driver.server or to complement a WebSocket client, a peer can make a single connection consume an unbounded...

CVE-2026-54399 Apache HttpComponents Core: Unbounded HTTP Header/Line Length in Default Configuration

Uncontrolled Resource Consumption vulnerability in the HTTP/1.1 message parser in Apache HttpComponents Core 5.4.2 and earlier, 5.5-beta1 and earlier allows an remote attacker to cause a denial of service through memory exhaustion by sending messages with excessive number of headers / excessive...

CVE-2026-54399

A remote attacker can cause a denial of service through memory exhaustion in Apache HttpComponents Core (versions 5.4.2 and earlier, and 5.5-beta1 and earlier). The root cause is an uncontrolled resource consumption vulnerability within the HTTP/1.1 message parser , triggered by sending messages ...

CVE-2026-53916 Apache ActiveMQ, Apache ActiveMQ All, Apache ActiveMQ Stomp: Unbounded header buffer in STOMP NIO codec

Memory Allocation with Excessive Size Value vulnerability in Apache ActiveMQ, Apache ActiveMQ All, Apache ActiveMQ Stomp. An unauthenticated client that opens a STOMP NIO connection can send header bytes that never terminate which makes the broker buffer them without limit, exhausting the JVM hea...

Netty: Unbounded pre-allocation in RedisArrayAggregator from RESP array length

Summary RedisArrayAggregator pre-allocates ArrayList with initial capacity equal to the RESP array element count declared in an array header. That count is taken from the wire before the corresponding child messages exist. A small malicious header can claim a huge initial capacity. Details The...

CVE-2026-44892

CVE-2026-44892 affects Netty’s HTTP/3 codec. Before 4.2.15.Final, Http3ConnectionHandler defaults allow an unbounded maximum header size when HTTP3_SETTINGS_MAX_FIELD_SECTION_SIZE isn’t specified, enabling a malicious peer to flood headers and cause memory exhaustion (OutOfMemoryError) with netwo...

CVE-2026-44892 Netty has a Vulnerable Default Configuration Which Leads to Denial of Service via Unbounded HTTP/3 Header Size

Netty is a network application framework for development of protocol servers and clients. Prior to version 4.2.15.Final, the default configuration of the Http3ConnectionHandler in the Netty HTTP/3 codec lacks an enforced maximum header size limit. When a peer does not explicitly specify...

CVE-2026-49754 HTTP/2 CONTINUATION flood in Mint client via unbounded header-block accumulation

Allocation of Resources Without Limits or Throttling vulnerability in elixir-mint Mint allows attacker-controlled HTTP/2 servers to exhaust memory in a Mint client HTTP/2 CONTINUATION flood. When Mint's HTTP/2 receive path observes a HEADERS frame without the ENDHEADERS flag, the unparsed...
