The vulnerability is a memory safety error (CWE\u2011416). When the bug is triggered the attacker\u2019s code runs with the privileges of the user who opens the corrupted document, potentially compromising confidential data, altering system state, or installing malware. The impact is therefore loss of confidentiality, integrity, and availability for the affected workstation. ", "risk_and_exploitability": "The CVSS score of 8.4 places this vulnerability in the high\u2011severity range, and while the EPSS score is less than 1% the existence of a public reference indicates that exploitation techniques are known. The issue is not listed in the CISA KEV catalog, suggesting that widespread exploitation has not yet been observed, but the bug can be triggered by a malicious document opened locally, making it trivial for an attacker to target unpatched users. The risk to an organization scales with the number of unsandboxed devices that may open unsolicited attachments, and the lack of an automatic update may prolong exposure."}}}}, "created": "2026-04-20T15:45:10.384932+00:00", "updated": "2026-04-20T15:45:10.384942+00:00", "vendors": []}
