CVE-2026-14539

The CVE affects Google mcp-toolbox versions up to 1.4.0, where the HTTP /mcp endpoint reads request bodies into memory using an unrestricted buffer (io.ReadAll) without limits. This unbounded buffering enables an unauthenticated attacker to cause a DoS by exhausting host memory, ultimately leadin...

JLSEC-2026-805 Apache Arrow: Potential use-after-free when reading IPC file with pre-buffering

Use After Free vulnerability in Apache Arrow C++. This issue affects Apache Arrow C++ from 15.0.0 through 23.0.0. It can be triggered when reading an Arrow IPC file but not an IPC stream with pre-buffering enabled, if the IPC file contains data with variadic buffers such as Binary View and String...

CVE-2026-56434

A vulnerability in NGINX's ngxhttpssimodule allows an unauthenticated MITM attacker to trigger a heap buffer over-read by manipulating upstream server responses. This requires SSI, proxypass, and proxybuffering off to be configured, and can result in memory modification or a Denial of Service DoS...

GHSA-G35J-M5XG-VH3Q webtransport-go: Memory Exhaustion Attack due to Buffering of Unknown Capsules

Summary An attacker can cause excessive memory allocation in webtransport-go by sending an unknown WebTransport capsule with a large payload. The implementation skips unknown capsules by reading the entire capsule body into memory, instead of draining it without retaining the data. This can lead ...

CVE-2026-56816

Netty is a network application framework for development of protocol servers and clients. Prior to 4.2.16.Final, Netty's Http3FrameCodec buffers incoming data for HTTP/3 reserved frame types up to the wire-specified payload length without limits; decodeFrame trusts payLoadLength, allowing an...

GDBusServer: glib2: GDBusServer pre-authentication DoS via unbounded SASL line buffering

A denial-of-service and resource exhaustion vulnerability exists within the GDBus component of GLib. The gdbusauth authentication mechanism fails to enforce proper length limitations on data lines read from a client. An unauthenticated local or remote attacker can exploit this lack of input...

BIT-NGINX-2026-56434 NGINX ngx_http_ssi_module vulnerability

NGINX Plus and NGINX Open Source have a vulnerability in the ngxhttpssimodule module. This vulnerability may exist when the Server-Side Includes SSI, proxypass, and proxybuffering off directives are configured. With this configuration, an unauthenticated attacker with man-in-the-middle MITM abili...

USN-8563-1: nginx vulnerabilities

It was discovered that nginx incorrectly handled certain map directives using regex matching and capture variables. A remote attacker could use this issue to cause nginx to crash, resulting in a denial of service, or possibly execute arbitrary code. CVE-2026-42533 It was discovered that nginx had...

CVE-2026-15588

CVE-2026-15588 affects GLib’s GDBus component. The gdbusauth mechanism fails to enforce length limits on data lines read from a client, enabling an unauthenticated attacker to trigger DoS and resource exhaustion by sending extremely long data streams. This can cause excessive memory and CPU consu...
