kernel: KVM: x86: Fix shadow paging use-after-free due to unexpected role

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM x86 shadow paging mechanism. This vulnerability occurs when a host page directory entry PDE mapping is changed from within the guest, leading to an unexpected role mismatch in shadow paging. This mismatch can cause a...

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...

GHSA-HX4H-VR3M-45VH n8n: Prototype Pollution via VM Expression Engine Sandbox Escape Leads to Denial of Service

Impact An authenticated user able to create or edit a workflow expression could abuse the expression engine's array-element access to obtain a reference to a host built-in and pollute its prototype in the main n8n process, leading to a denial of service. Both self-hosted and cloud instances runni...

GHSA-Q3J5-8VRG-4P9Q n8n: Shared Credential Header Leak via HTTP Request Pagination Expression

Impact An authenticated member with use-only editor access to a shared workflow could read credential-populated headers exposed via the $request object inside an HTTP Request node's pagination expression. When an HTTP Header Auth credential is applied to a paginated request, the secret is present...

GHSA-558V-64GR-WGG4 Netty: [Bzip2Decoder] Infinite Loop in RLE State Machine Leads to Event-Loop Thread Hang

The Bzip2Decoder handler in Netty's compression codec pipeline is vulnerable to a denial-of-service attack through a malformed bzip2 stream that permanently captures the event-loop thread in an infinite loop. The vulnerability exists in the run-length encoding RLE state machine within...
