Eclipse Vert.x 安全漏洞

Eclipse Vert.x is a toolkit developed by the Eclipse Foundation for building responsive applications on the JVM. There is a security vulnerability in Eclipse Vert.x, which stems from the fact that the TCP client can perform TLS handshakes and present server name extensions. These server name...

tomcat: Client certificate verification bypass due to virtual host mapping

A certificate validation flaw has been found in Apache Tomcat. omcat did not validate that the host name provided via the SNI extension was the same as the host name provided in the HTTP host header field. If Tomcat was configured with more than one virtual host and the TLS configuration for one ...

wrong reuse of SMB connection

libcurl might in some circumstances reuse the wrong connection for SMBS transfers. libcurl features a pool of recent connections so that subsequent requests can reuse an existing connection to avoid overhead. When reusing a connection a range of criteria must be met. Due to a logical error in the...

pyOpenSSL: TLS connection bypass via unhandled callback exception in set_tlsext_servername_callback

A flaw was found in pyOpenSSL. The settlsextservernamecallback callback function can be used to implement Server Name Indication SNI during the TLS handshake. When the callback raises an unhandled exception, the handshake incorrectly proceeds instead of terminating. This fail-open behavior can...

FastMCP 操作系统命令注入漏洞

FastMCP is a MCP server building software developed by Jeremiah Lowin. Versions of FastMCP prior to 3.2.0 contained an operating system command injection vulnerability. This vulnerability could be exploited when a server name containing a shell metacharacter was used; commands could be executed o...

GHSA-M8X7-R2RG-VH5G FastMCP has a Command Injection vulnerability - Gemini CLI

Server names containing shell metacharacters e.g., & can cause command injection on Windows when passed to fastmcp install claude-code or fastmcp install gemini-cli. These install paths use subprocess.run with a list argument, but on Windows the target CLIs often resolve to .cmd wrappers that are...
