Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check WinRAR version via Help menuOpen WinRAR, click Help menu, then About WinRAR to view the version number displayed in the dialogAffected if The displayed version is below 7.13 (for example, 7.12, 7.10, 6.x, etc.)
-
Check WinRAR version from executable propertiesLocate winrar.exe (typically in C:\Program Files\WinRAR or C:\Program Files (x86)\WinRAR), right-click, select Properties, and view the version in the Details tabAffected if The File version shown is less than 7.13.0.0
-
Check WinRAR version via command lineOpen Command Prompt or PowerShell, navigate to the WinRAR installation directory, and run: winrar -ver or winrar /?Affected if The reported version number is lower than 7.13
If WinRAR version is below 7.13, the environment is affected by this path traversal vulnerability when extracting archives from untrusted sources.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped7.132023.01
Apply the vendor patch for WinRAR as soon as it becomes available; until then, exercise extreme caution with archive files from untrusted sources and consider blocking or monitoring RAR file handling in enterprise environments.
WinRAR 7.13
- Download WinRAR version 7.13 or later from the official WinRAR website (www.win-rar.com)
