Name of the Vulnerable Software and Affected Versions: encfs versions prior to 1.7.5

Description: The issue allows remote attackers to access sensitive data by modifying the ".encfs6.xml" configuration file. Specifically, setting blockMACBytes to 0 and adding 8 to blockMACRandBytes enables this unauthorized access.
