CVE-2022-4220: Chained Quiz <= 1.3.2.4 - Cross-Site Request Forgery to Question Deletion

The Chained Quiz plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.3.2.4. This is due to missing nonce validation on the list_questions() function. This makes it possible for unauthenticated attackers to delete questions from quizzes via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Security readout for executives and security teams

Plain-English summary

CVE-2022-4220 lets an attacker trick a WordPress administrator into triggering deletion of Chained Quiz questions. The attacker does not need an account, but the attack depends on administrator interaction. Business impact is content loss or quiz disruption, not data theft based on the supplied sources.

Executive priority

Treat this as a moderate website integrity issue. Prioritize sites that rely on quizzes for revenue, training, lead capture, or compliance evidence. It is not described as data theft or server takeover in the supplied sources.

Technical view

Chained Quiz for WordPress through version 1.3.2.4 lacks nonce validation in list_questions(), creating a CSRF path to delete quiz questions. The CVSS 3.1 score is 5.4 with network attack vector, low complexity, no privileges, required user interaction, and low integrity and availability impact.

Likely exposure

Exposure is limited to WordPress sites with the Chained Quiz plugin installed at versions up to and including 1.3.2.4. Sites not using this plugin are not exposed based on the supplied bundle.

Exploitation context

CISA KEV is false in the bundle, and no supplied source states active exploitation. The described attack requires deceiving a site administrator into performing an action that sends a forged request.

Researcher notes

The key condition is missing nonce validation in list_questions(). The source bundle identifies question deletion as the impact and administrator interaction as required. A public gist is referenced, but the bundle does not establish active exploitation.

Mitigation direction

  • Inventory WordPress sites for the Chained Quiz plugin and installed version.
  • Update Chained Quiz if vendor guidance provides a release newer than 1.3.2.4.
  • If no supported update is available, disable or remove the plugin.
  • Limit WordPress administrator access to trusted users.
  • Warn administrators against clicking unexpected links while authenticated.

Validation and detection

  • Confirm whether Chained Quiz is installed on each WordPress site.
  • Check plugin version and flag versions up to 1.3.2.4.
  • Review quiz question records for unexpected deletions or gaps.
  • Review WordPress admin activity around reported content loss.
  • Verify vendor or WordPress plugin guidance before declaring remediation complete.
