Beschreibung
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.
