CVE-2025-26624 is a medium-severity vulnerability rated 6.8/10 on the CVSS scale. 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. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
