CVE-2025-26624
Local Privilege Escalation in Rufus 4.6 and previous versions
Rufus is a utility that helps format and create bootable USB flash drives. A DLL hijacking vulnerability in Rufus 4.6.2208 and earlier versions allows an attacker loading and executing a malicious DLL with escalated privileges (since the executable has been granted higher privileges during the time of launch) due to the ability to inject a malicious cfgmgr32.dll in the same directory as the executable and have it side load automatically. This is fixed in commit 74dfa49, which will be part of version 4.7. Users are advised to upgrade as soon as version 4.7 becomes available. There are no known workarounds for this vulnerability.
