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.
-
Verify HYPR Workforce Access is installedCheck for the presence of HYPR Workforce Access on the Windows system through Programs and Features, the installation directory, or by searching for hypr or workforce access in installed programsAffected if The software is not found, the check cannot be completed
-
Locate the installed version numberFind the version information - typically via the application's executable properties (right-click the .exe file), in the Windows registry under the uninstall key for HYPR, or within the application's About/Help sectionAffected if The version cannot be determined from the installed instance
-
Compare version to the affected rangeReview the installed version number and compare it against version 8.7 - any version less than 8.7 (such as 8.6.x, 8.5.x, or earlier) falls within the affected rangeAffected if The installed version is below 8.7 (for example: 8.6, 8.5.1, 8.0, etc.)
-
Confirm the Windows platformVerify the affected system is running Windows, as this vulnerability specifically impacts the Windows version of HYPR Workforce AccessAffected if The software is running on a non-Windows platform, the specific vulnerability does not apply
The environment is affected only if HYPR Workforce Access is installed on Windows with a version number less than 8.7.
