CVE-2026-44612
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 · uneditedBytello Share (Windows Edition) installer executable provided by Bytello insecurely loads Dynamic Link Libraries. If there is a crafted DLL at the same directory when invoking the affected installer, arbitrary code may be executed with the privilege of the user invoking the installer.
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 · high confidenceBytello Share Windows installer is vulnerable to DLL hijacking due to insecure DLL loading - it attempts to load Dynamic Link Libraries without using fully qualified paths, allowing an attacker to place a malicious DLL in the same directory as the installer to achieve arbitrary code execution with the privileges of the user running the installer.

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.
-
Locate Bytello Share installer on the systemSearch for Bytello Share installer files (typically named BytelloShare*.exe or similar) in download folders, temp directories, or installation staging areas. Also check for the installed application in Program Files.Affected if Bytello Share installer or installed application is present on the system
-
Identify the installed versionCheck the version of the Bytello Share installation: look in Windows Registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for Bytello Share entry, or check the version property of the executable in the installation folder.Affected if Version information cannot be verified or no patched version is confirmed by the vendor
-
Review installer directory for foreign DLLsExamine the directory from which the installer was run. List all DLL files present in that directory and verify they are legitimate Microsoft or Bytello DLLs by checking their digital signatures or known file hashes.Affected if Any unknown or unsigned DLL files exist in the same directory as the Bytello Share installer
-
Check installer execution contextDetermine if the installer was run from a directory with world-write permissions (such as downloads, temp folders, or network shares) where an untrusted user could place files.Affected if The installer was executed from a directory accessible to other users or processes who could inject a malicious DLL
If you have run the Bytello Share Windows installer from any directory where an untrusted DLL could have been placed, you may be vulnerable to arbitrary code execution via DLL hijacking.

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.
From vendor dataUsers should only download and run the installer from trusted sources and ensure no untrusted files exist in the installer directory. Organizations should verify installer integrity via checksums and obtain updates directly from the vendor once available.
