The flaw is linked to CWE-284, a weakness that allows privilege escalation through improper access control. Because the sandbox is designed to isolate applications, an escape could provide an attacker with the ability to read or modify data outside the application\u2019s allowed scope, potentially compromising user data and system integrity.", "risk_and_exploitability": "The CVSS score of 5.2 indicates moderate severity, while the EPSS score of less than 1% signifies a very low, yet non-zero, likelihood of current exploitation. The vulnerability is not listed in the CISA KEV catalog.
