id: CVE-2021-24915

info:
  name: Contest Gallery < 13.1.0.6 - SQL injection
  author: r3Y3r53
  severity: critical
  description: |
    The plugin does not have capability checks and does not sanitise or escape the cg-search-user-name-original parameter before using it in a SQL statement when exporting users from a gallery, which could allow unauthenticated to perform SQL injections attacks, as well as get the list of all users registered on the blog, including their username and email address.
  remediation: Fixed in version 13.1.0.6
