The flaw arises from an unescaped %{expr} injection in the tabpanel configuration when the P_MLE flag is absent, allowing shell commands to be evaluated in the user\u2019s environment. If exploited, the attacker achieves full code execution under the current user\u2019s privileges, compromising the session and potentially the underlying system.", "risk_and_exploitability": "The CVSS score of 9.2 categorizes this vulnerability as critical. An EPSS score is not available, and the issue is not listed in the CISA KEV catalog. Exploitation is local: the victim must open the crafted file; no network or privilege escalation mechanism is required beyond that. Because the injected command runs with the current process\u2019s privileges, a local attacker can gain full control of the system once the file is opened, making it a high\u2011risk threat for unpatched users."}}}}, "created": "2026-03-31T20:00:11.744603+00:00", "updated": "2026-03-31T20:40:29.593984+00:00", "vendors": ["vim", "vim$PRODUCT$vim"]}
