kernel: nfsd: fix heap overflow in NFSv4.0 LOCK replay cache

A flaw was found in the Linux kernel's NFSv4.0 server nfsd. A remote, unauthenticated attacker can exploit this heap overflow vulnerability in the NFSv4.0 LOCK replay cache. By using two cooperating NFSv4.0 clients, where one sets a lock with a large owner string and another requests a conflictin...

OpenClaw 安全漏洞

OpenClaw is an intelligent artificial assistant open-sourced by OpenClaw. OpenClaw suffers from a security vulnerability that stems from the derivation of a loopback MCP owner context from a server-issued bearer token that can be spoofed in the request header, which can be exploited by an attacke...

DevGuard has an unauthenticated identity assertion via `X-Admin-Token` header

Impact The SessionMiddleware accepts a client-supplied X-Admin-Token HTTP request header and uses its raw string value as the authenticated userID when no Kratos session cookie is present.
