CVE:CVE-2026-48529 vulnerable 2026-07-29 00:55:01.390587 GitHub MCP Server: Lockdown mode singleton in HTTP server causes cross-user GraphQL client confusion
MEDIUM (6)
GitHub MCP Server is GitHub's official MCP Server. From 0.22.0 until 1.1.2, when running in HTTP mode with --lockdown-mode enabled, the RepoAccessCache is implemented as a process-global singleton initialized with the first authenticated user's GraphQL client. All subsequent requests from different users share this singleton and their lockdown-related GraphQL queries are executed using the first user's credentials. The singleton is never updated to reflect later users' tokens. This vulnerability is fixed in 1.1.2.
