The issue concerns modules dynamically imported through `import()` or `new Worker` that might bypass network and file system permission checks when statically importing other modules. An attacker in control of a module in a program's module graph could initiate GET requests to arbitrary URLs and possibly read the contents of these resources, or check for existence of arbitrary paths on the file system and possibly read the contents of these files. This vulnerability was not present in releases prior to 1.5.0 and was not abused in the wild, as indicated by the lack of reports and the default behavior of Deno printing a "Download" message when remote imports are downloaded.
