CVE-2022-4211

Name of the Vulnerable Software and Affected Versions Chained Quiz plugin for WordPress versions up to, and including, 1.3.2

Description The issue is related to Reflected Cross-Site Scripting due to insufficient input sanitization and output escaping. This allows unauthenticated attackers to inject arbitrary web scripts in pages via the emailf parameter on the "chainedquiz list" page, potentially executing if a user is tricked into performing an action like clicking on a link.

Recommendations For versions up to, and including, 1.3.2, update to a version higher than 1.3.2 to resolve the issue. As a temporary workaround, consider restricting access to the "chainedquiz list" page and avoiding use of the emailf parameter until a patch is available.
