This weakness permits an attacker to retrieve confidential information without the user\u2019s awareness, potentially compromising privacy and integrity of personal or corporate data. The vulnerability aligns with CWE\u2011200, an information exposure flaw that can lead to unauthorized data disclosure.", "risk_and_exploitability": "The CVSS score of 9.8 indicates critical severity, but the EPSS score of less than 1% suggests a very low probability of active exploitation at the time of analysis. This vulnerability is not listed in the CISA KEV catalog. The potential attack vector is a local or user\u2011directed scenario where the victim runs a malicious application. An adversary would need to deliver or trick the user into installing a downgraded app that bypasses code\u2011signing checks, after which the app can read protected data. Because no known public exploits are available and exploitation would likely require user interaction, the risk remains moderate to high depending on the environment."}}}}, "created": "2026-04-28T04:15:16.041407+00:00", "title": "Downgrade Issue Lets App Access Sensitive User Data", "updated": "2026-04-28T04:15:16.041422+00:00", "vendors": []}
