Folder Lock v3.4.5 was discovered to contain a stored cross-site scripting (XSS) vulnerability in the Create Folder function under the 'create' module. This vulnerability allows attackers to execute arbitrary web scripts or HTML via a crafted payload as a path or folder name.

Folder Lock 5.9.5 and earlier uses weak encryption (ROT-25) for the password, which allows local administrators to obtain sensitive information by reading and decrypting the QualityControl\_pack registry value.
