CVE-2026-26306

Arbitrary code execution via installer DLL hijacking

Published Mar 25, 2026 · Updated Mar 25, 2026

Uncontrolled DLL loading in OM Workspace for Windows 2.4 and earlier allows attackers to execute code through a crafted local DLL. The installer searches its own directory for a required DLL and loads a malicious file placed there instead of restricting resolution to a trusted path. Exploitation requires a user to download the crafted DLL into the installer's directory and run the affected installer; code runs with that user's privileges.
