Descripción técnica

TinyWeb through 0.0.8 contains a null pointer dereference vulnerability that allows unauthenticated remote attackers to crash worker processes by sending a malformed HTTP request line with an invalid version string. The HttpParser::execute() function fails to allocate the Url object when version parsing fails, leaving the url pointer NULL, and buildResponse() subsequently dereferences this NULL pointer without checking the valid_requ flag, producing a SIGSEGV that terminates the worker process and, when repeated across all workers, takes the server permanently offline until manually restarted.

——0Let's Chat 0.4.0 through 0.4.8 contains a null dereference vulnerability that allows authenticated attackers to crash the server by supplying a valid 24-character hex string room parameter that matches no document in the database. Attackers can send a crafted GET /messages request causing an uncaught TypeError in an asynchronous Mongoose callback that terminates the Node.js server process, with the same defect reachable through multiple code paths including the socket.io interface.19h CVE-2026-474277.5 ALT

——0GitHub MCP Server is GitHub's official MCP Server. Prior to 1.1.0, the CompletionsHandler function in pkg/github/server.go accesses params.Ref without first checking whether it is nil, so a completion/complete request with a missing or empty ref field triggers a nil pointer dereference and a Go runtime panic; because the crash occurs before any authentication or token validation, any unauthenticated client able to send JSON-RPC messages can crash the server, resulting in a complete denial of service. This issue is fixed in version 1.1.0.18h CVE-2026-17574—

——14NULL Pointer Dereference vulnerability in Apache NimBLE in LE Long Term Key Request event.

Users are recommended to upgrade to version 1.10.0, which fixes the issue.2d
