Memcached version 1.5.5 contains an Insufficient Control of Network Message Volume (Network Amplification, CWE-406) vulnerability in the UDP support of the memcached server that can result in denial of service via network flood (traffic amplification of 1:50,000 has been reported by reliable sources).

CVE-2025-68272HIGH 7.5

Signal K Server is a server application that runs on a central hub in a boat. A Denial of Service (DoS) vulnerability in versions prior to 2.19.0 allows an unauthenticated attacker to crash the SignalK Server by flooding the access request endpoint (`/signalk/v1/access/requests`). This causes a "JavaScript heap out of memory" error due to unbounded in-memory storage of request objects. Version 2.19.0 fixes the issue.

Vulnerability in CIRCUTOR TCP2RS+ firmware version 1.3b, which could allow an attacker to modify any configuration value, even if the device has the user/password authentication option enabled, without authentication by sending packets through the UDP protocol and port 2000, deconfiguring the device and thus disabling its use. This equipment is at the end of its useful life cycle.

A vulnerability in gaizhenbiao/chuanhuchatgpt version 20240410 allows any user to restart the server at will by sending a specific request to the `/queue/join?` endpoint with `"fn_index":66`. This unrestricted server restart capability can severely disrupt service availability, cause data loss or corruption, and potentially compromise system integrity.
