WordPress · Yop Poll · CVE-2021-24834
**Name of the Vulnerable Software and Affected Versions**
YOP Poll versions prior to 6.3.1
**Description**
The issue is related to a stored Cross-Site Scripting vulnerability in the Create Poll - Options module of the YOP Poll WordPress plugin. This vulnerability exists due to insufficient validation of custom label parameters, specifically the `vote button label`, `results link label`, and `back to vote caption label`. This allows a user with a role as low as author to execute arbitrary script code within the context of the application, potentially leading to remote exploitation.
**Recommendations**
For versions prior to 6.3.1, update to version 6.3.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the Create Poll - Options module or disabling the execution of custom label parameters until a patch is applied. Avoid using the parameters `vote button label`, `results link label`, and `back to vote caption label` in the affected module until the issue is resolved.
