Submit #813980: debugmcp mcp-debugger 3e83906c8358965efd683c734e94a75d338400fa Path Traversalinfo

Titeldebugmcp mcp-debugger 3e83906c8358965efd683c734e94a75d338400fa Path Traversal
BeschreibungA path traversal / arbitrary file read issue exists in debugmcp/mcp-debugger (tested on commit 3e83906c8358965efd683c734e94a75d338400fa). The source-context flow accepts user-controlled file input via handleGetSourceContext. In host mode, resolvePathForRuntime returns input paths unchanged, and the effective path reaches filesystem operations (readFile/stat/pathExists) without workspace boundary enforcement. This allows unauthorized reading of arbitrary absolute filesystem paths.
