  "summary": "CVE-2023-38831 is fixed in WinRAR on 1 platform by WinRAR 6.23.0 (version 6.23.0), released August 2, 2023. It is being exploited: CISA added it to the Known Exploited Vulnerabilities catalog on August 24, 2023, with known ransomware use. Patch Radar priority: Patch now.",
  "title": "RARLAB WinRAR Code Execution Vulnerability",
  "description": "RARLAB WinRAR before 6.23 allows attackers to execute arbitrary code when a user attempts to view a benign file within a ZIP archive. The issue occurs because a ZIP archive may include a benign file (such as an ordinary .JPG file) and also a folder that has the same name as the benign file, and the contents of the folder (which may include executable content) are processed during an attempt to access only the benign file. This was exploited in the wild in April through October 2023.",
