This creates a risk of confidential information being exposed to apps that should not have such access, potentially leaking personal or sensitive data. The weakness maps to information exposure, as it directly lets a process discover data stored in caches that are intended to be protected.", "risk_and_exploitability": "The CVSS score of 5 indicates a moderate severity vulnerability, while the EPSS score of less than 1% suggests a low probability of exploitation in the near term. The vulnerability is not currently documented in the CISA KEV catalog. The likely attack scenario involves a compromised or malicious application accessing the cache to retrieve protected data; no explicit remote exploit path is described, so the threat is most pronounced in local or privileged contexts."}}}}, "created": "2025-12-18T09:55:36.062139+00:00", "title": "macOS Cache Access Allows Information Disclosure", "updated": "2026-04-27T22:15:15.126364+00:00", "vendors": ["apple", "apple$PRODUCT$macos", "apple$PRODUCT$macos_tahoe"]}
