  MyBB is prone to multiple security vulnerabilities. These vulnerabilities include a username-enumeration weakness, an XML-injection vulnerability, and a cross-site scripting vulnerability.
  
  Exploiting these issues may allow attackers to discern valid usernames, which may aid them in brute-force password cracking or other attacks. Attacker-supplied XML and script code would run in the context of the affected browser, potentially allowing the attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user.
  
  Versions prior to 1.6.2 and 1.4.15 are vulnerable. 
  
  XML-injection:

  XSS:
