Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedStudio Network Solutions ShareBrowser before 7.0 on macOS mishandles signature verification, aka PMP-2636.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceStudio Network Solutions ShareBrowser before version 7.0 on macOS contains a vulnerability where signature verification is mishandled, allowing attackers to potentially bypass cryptographic integrity checks. This critical flaw (CVSS 9.8) likely enables remote code execution or authentication bypass by exploiting improper validation of digital signatures.

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 if ShareBrowser is installedOpen Terminal and run: ls /Applications/ | grep -i sharebrowser or look for 'ShareBrowser' in the Applications folderAffected if ShareBrowser exists in the Applications directory
-
Determine the installed versionRun: defaults read /Applications/ShareBrowser.app/Contents/Info CFBundleShortVersionString 2>/dev/null or right-click ShareBrowser.app > Get Info to view VersionAffected if The version number returned is less than 7.0 (e.g., 6.x, 5.x, etc.)
-
Verify the exact version stringRun: mdls -name kCFBundleShortVersionString /Applications/ShareBrowser.app 2>/dev/nullAffected if The version shown is any version prior to 7.0, such as 6.5.2, 6.4.0, or earlier
-
Confirm the vendor and application nameRun: mdls -name kCFBundleName /Applications/ShareBrowser.app 2>/dev/nullAffected if The bundle name confirms this is 'ShareBrowser' by Studio Network Solutions
You are affected if ShareBrowser is installed on macOS and the version is any release prior to 7.0, as only version 7.0 and later contain the corrected signature verification logic.
