Vulnerability Title
check-jsonschema default caching for remote schemas allows for cache confusion
Vulnerability Description
check-jsonschema is a CLI and set of pre-commit hooks for jsonschema validation. 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, e.g., `https://example.evil.org/schema.json`, they can insert their own schema into the cache and it will be picked up and used instead of the appropriate schema. Such a cache confusion attack could be used to allow data to pass validation which should have been rejected. This issue has been patched in version 0.30.0. All users are advised to upgrade. A few workarounds exist: 1. Users can use `--no-cache` to disable caching. 2. Users can use `--cache-filename` to select filenames for use in the cache, or to ensure that other usages do not overwrite the cached schema. (Note: this flag is being deprecated as part of the remediation effort.) 3. Users can explicitly download the schema before use as a local file, as in `curl -LOs https://example.org/schema.json; check-jsonschema --schemafile ./schema.json`

check-jsonschema 安全漏洞
Vulnerability Description
check-jsonschema是Python + JSON Schema开源的一个用于 jsonschema 验证的 CLI。 check-jsonschema存在安全漏洞，该漏洞源于默认缓存策略使用远程架构的基本名称作为缓存中文件的名称，例如https://example.org/schema.json将存储为schema.json。
