GHSA-7488-6R32-C95Q LiteLLM: MCP Authentication Bypass via OAuth2 Passthrough Fallback

Impact LiteLLM's MCP Streamable HTTP endpoint could allow an unauthenticated attacker to establish an authenticated MCP session using an arbitrary Bearer token. The MCP auth handler supported OAuth2 passthrough for upstream MCP servers, but the fallback path could replace failed LiteLLM key...

CVE-2026-49353

Summary (CVE-2026-49353): 9Router before 0.4.46 has a local‑only access gate in src/dashboardGuard.js that relies on Host and Origin headers to classify requests as local. In proxied/tunneled deployments (reverse proxy, Cloudflare Tunnel, Tailscale), these headers are attacker‑controlled, enablin...

CVE-2026-49353 9Router: Local-Only Access Gate Bypass in 9router via Host Header SpoofING

9Router is an AI router & token saver. In 0.4.45 and earlier, 9Router's src/dashboardGuard.js local-only access gate used Host and Origin headers in isLocalRequest to protect /api/mcp/, /api/tunnel/, and /api/cli-tools/, allowing header spoofing in reverse proxy or tunnel deployments to reach MCP...

CVE-2026-46339 9Router: Unauthenticated Remote Code Execution via unprotected MCP custom plugin routes

9Router is an AI router & token saver. From 0.4.30 until 0.4.37, 9Router's src/proxy.js middleware did not protect /api/cli-tools/ and /api/mcp/, allowing unauthenticated registration of customPlugins through src/app/api/cli-tools/cowork-settings/route.js and command execution through the MCP...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM – Avoid clearing VMCBLBR in vmcb12. The svmcopylbrs function always marks VMCBLBR as dirty in the destination VMC. However, nestedsvmvmexit uses it to copy LBRs to vmcb12, and clearing the “clean” bits in vmcb12 is not...

CVE-2026-53840 OpenClaw < 2026.5.12 - Custom Header Leakage via MCP Streamable HTTP Cross-Origin Redirects

OpenClaw before 2026.5.12 contains an information disclosure vulnerability in streamable-http MCP servers that forwards operator-configured custom headers during cross-origin redirects. Attackers controlling or compromising an MCP endpoint can redirect requests to exfiltrate sensitive headers lik...
