id: CVE-2024-7786

info:
  name: Sensei LMS < 4.24.2 - Email Template Leak
  author: s4e-io
  severity: high
  description: |
    The Sensei LMS WordPress plugin before 4.24.2 does not properly protect some its REST API routes, allowing unauthenticated attackers to leak email templates.
  impact: |
    Unauthenticated attackers can access and leak email templates through unprotected REST API endpoints, potentially exposing sensitive information included in email communications and template configurations.
  remediation: |
    Update Sensei LMS plugin to version 4.24.2 or later to address the REST API protection issue.
