CVE-2025-68594 identifies a missing authorization vulnerability in the Poll, Survey & Quiz Maker Plugin by Opinion Stage, developed by Assaf Parag. This vulnerability arises from incorrectly configured access control security levels, which fail to properly restrict user permissions within the plugin. As a result, unauthorized users could exploit this flaw to perform actions that should be limited to privileged roles, such as administrators. The affected versions include all releases up to and including 19.12.1. The vulnerability does not require user interaction but does depend on the attacker having some level of access to the WordPress environment where the plugin is installed. Since the plugin is commonly used to create interactive polls, surveys, and quizzes, exploitation could lead to unauthorized data access, manipulation of survey results, or disruption of polling functionality. No CVSS score has been assigned yet, and no public exploits have been reported. The vulnerability was published on December 24, 2025, with the issue reserved a few days earlier. The lack of patch links suggests that a fix may not yet be available, emphasizing the need for immediate mitigation steps by administrators. The plugin’s widespread use in WordPress environments, particularly in Europe, increases the potential attack surface. Attackers could leverage this vulnerability to undermine data integrity or gain unauthorized insights into collected data, impacting organizational decision-making and user trust.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of data collected through the Opinion Stage plugin. Unauthorized access could lead to exposure of sensitive survey or poll data, manipulation of results, or unauthorized changes to plugin configurations. This could damage organizational reputation, lead to compliance violations (especially under GDPR if personal data is involved), and disrupt business operations reliant on accurate survey data. Organizations using this plugin for customer feedback, employee engagement, or market research are particularly vulnerable. The absence of a patch increases the window of exposure, and the potential for attackers to exploit missing authorization means that even low-privileged users or external attackers with limited access could escalate privileges or perform unauthorized actions. This could also serve as a foothold for further attacks within the affected WordPress environment. Given the plugin’s integration with websites, availability impacts could arise if attackers disrupt polling or survey functionalities, affecting user experience and trust.

European organizations should immediately audit and restrict access permissions for the Poll, Survey & Quiz Maker Plugin by Opinion Stage, ensuring only trusted administrators have plugin management rights. Disable or uninstall the plugin if it is not essential. Monitor WordPress logs and plugin activity for unusual access patterns or unauthorized changes. Implement web application firewalls (WAFs) with rules to detect and block suspicious requests targeting the plugin endpoints. Regularly back up survey and poll data to enable recovery in case of tampering. Stay informed on vendor announcements for official patches and apply updates promptly once available. Consider isolating the plugin environment or deploying it in a sandboxed context to limit potential damage. Educate administrators on the risks of misconfigured access controls and enforce strong authentication mechanisms for WordPress admin accounts. If feasible, conduct penetration testing focused on plugin access controls to identify and remediate weaknesses proactively.
