Technical Details of CVE-2022-0205

Let's explore the technical aspects of this vulnerability, including a description of the issue, the affected systems, vulnerable versions, and the exploitation mechanism.

Vulnerability Description

The flaw in the YOP Poll plugin version prior to 6.3.5 allows attackers, with at least author-level access, to insert harmful scripts that get executed when other users interact with affected poll settings.

Affected Systems and Versions

YOP Poll versions earlier than 6.3.5 are vulnerable to this Stored Cross-Site Scripting issue. Websites using these versions are at risk of exploitation.
