CVE-2022-4215: Chained Quiz <= 1.3.2.3 - Reflected Cross-Site Scripting via date

The Chained Quiz plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'date' parameter on the 'chainedquiz_list' page in versions up to, and including, 1.3.2.3 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

Security readout for executives and security teams

Plain-English summary

CVE-2022-4215 is a reflected cross-site scripting issue in the WordPress Chained Quiz plugin through version 1.3.2.3. An attacker does not need an account, but must trick a user into opening a crafted link. Successful exploitation could run script in the user’s browser and affect confidentiality or integrity at a limited level.

Executive priority

Treat as a moderate web application risk. It is not listed as KEV exploited, but public details exist and unauthenticated attackers can attempt phishing-style delivery against affected WordPress users.

Technical view

The flaw is CWE-79 in the Chained Quiz plugin’s handling of the date parameter on the chainedquiz_list page. Sources attribute it to insufficient input sanitization and output escaping. CVSS 3.1 is 6.1, network exploitable with low attack complexity, no privileges required, user interaction required, changed scope, and low confidentiality and integrity impact.

Likely exposure

Exposure is limited to WordPress sites running the Chained Quiz plugin versions up to and including 1.3.2.3. The bundle does not show evidence that other products are affected.

Exploitation context

The source bundle includes a public proof-of-concept reference, but KEV is false and no cited source states active exploitation. Exploitation requires a user to take an action such as clicking a link.

Researcher notes

Focus validation on reflected output of the date parameter on chainedquiz_list and whether current code sanitizes input and escapes output. Avoid assuming exploitation without telemetry; the bundle only supports public disclosure and proof-of-concept existence.

Mitigation direction

  • Inventory WordPress sites for the Chained Quiz plugin and its installed version.
  • Update Chained Quiz to a version newer than 1.3.2.3 if available from official sources.
  • If no safe update is available, follow vendor guidance or consider disabling the plugin.
  • Prioritize sites where privileged users may access plugin pages from email or external links.

Validation and detection

  • Confirm whether each WordPress site has Chained Quiz installed.
  • Verify installed plugin versions are not 1.3.2.3 or earlier.
  • Review the vendor changelog or WordPress changeset for sanitization and escaping changes.
  • Check whether chainedquiz_list exposure is reachable by users in your environment.
