Critical RAR Security Vulnerability affects older dtSearch for Windows versions

Article: dts0245

Applies to: dtSearch 2022.02 and earlier

CVE-2025-8088, a security vulnerability affecting the library that dtSearch uses to process RAR files, affects dtSearch versions 2022.02 and earlier.  Users with affected versions should update immediately.  To update, run dtSearch Desktop and click Help > Check for Updates > Check Now.

Only Windows versions are affected.  Another way to eliminate the vulnerability is to delete the files dtv_rar.dll and dtv_rar64.dll from your dtSearch installation.

For more information on this vulnerability, see: https://www.cve.org/CVERecord?id=CVE-2025-8088

The vulnerability only affects older dtSearch versions because we removed the related code from dtSearch products before the release of dtSearch 2023.01.  

Another recent RAR vulnerability, CVE-2025-6218, does not affect dtSearch because dtSearch ignores the archive-supplied extraction path.
