  "bluf": "MITRE CAPEC-48 (Passing Local Filenames to Functions That Expect a URL) is a standard-level attack pattern in the MITRE Common Attack Pattern Enumeration and Classification. This attack relies on client side code to access local files and resources instead of URLs. When the client browser is expecting a URL string, but instead receives a request for a local file, that execution is likely to occur in the browser process space with the browser's authority to local files. The attacker can send the results of this request to the local files out to a site that they control. Likelihood of attack: High. Typical severity: High. Maps to weaknesses CWE-241, CWE-706.",
