I am reporting it privately here first because it is an unfixed security issue. `McpContext.validatePath()` enforces workspace `roots` by checking whether `path.resolve(filePath)` textually falls under one of the configured root paths. `path.resolve()` does

Because the write does not use `O_NOFOLLOW`, a local low-privilege user on the same POSIX host can pre-create `/tmp/chrome-devtools-mcp-<victim_uid>/daemon.pid` as a symlink to a file writable by the victim.
