PYSEC-2026-1245 check-jsonschema default caching for remote schemas allows for cache confusion

Impact The default cache strategy uses the basename of a remote schema as the name of the file in the cache, e.g. https://example.org/schema.json will be stored as schema.json. This naming allows for conflicts. If an attacker can get a user to run check-jsonschema against a malicious schema URL,...
