CVE-2025-68594 identifies a missing authorization vulnerability in the Assaf Parag Poll, Survey & Quiz Maker Plugin by Opinion Stage, a popular WordPress plugin used for creating polls, surveys, and quizzes. The vulnerability arises from incorrectly configured access control security levels, allowing attackers with low privileges (PR:L) to bypass authorization checks and perform unauthorized actions remotely over the network (AV:N) without requiring user interaction (UI:N). The vulnerability affects all versions up to and including 19.12.1. The CVSS 3.1 base score of 8.1 reflects a high severity due to the potential for complete compromise of confidentiality and integrity of data handled by the plugin, although availability is not impacted. Attackers exploiting this flaw could manipulate survey data, extract sensitive information, or alter poll results, undermining trust and data accuracy. The vulnerability does not require user interaction, increasing the risk of automated exploitation. No patches or exploit code are currently publicly available, but the plugin’s widespread use in WordPress environments makes this a critical issue to address promptly. The vulnerability was reserved and published in December 2025, indicating recent discovery and disclosure.

For European organizations, especially those using WordPress-based websites with the Opinion Stage plugin, this vulnerability poses a significant risk to data confidentiality and integrity. Attackers could manipulate survey or poll data, potentially influencing business decisions, customer feedback analysis, or public opinion metrics. Confidential information collected through surveys could be exposed, leading to privacy violations and regulatory non-compliance under GDPR. The integrity compromise could damage organizational reputation and trustworthiness. Since availability is not affected, denial-of-service is unlikely, but the unauthorized data manipulation and leakage risks are substantial. Organizations relying on these plugins for customer engagement, market research, or internal feedback mechanisms are particularly vulnerable. The lack of known exploits in the wild currently provides a window for proactive mitigation, but the ease of exploitation and network accessibility heighten the urgency.

1. Immediately verify the plugin version installed on all WordPress sites and plan for an upgrade to a patched version once released by the vendor. 2. Until patches are available, restrict access to plugin management interfaces strictly to trusted administrators using role-based access controls. 3. Implement web application firewall (WAF) rules to monitor and block suspicious requests targeting the plugin endpoints. 4. Conduct regular audits of user privileges to ensure no unnecessary low-privilege accounts can access sensitive plugin functions. 5. Monitor logs for unusual activity related to the plugin, such as unauthorized API calls or changes to poll/survey data. 6. Consider temporarily disabling the plugin if it is not critical to business operations until a secure version is deployed. 7. Educate site administrators about the risks and signs of exploitation attempts. 8. Employ intrusion detection systems (IDS) tuned to detect exploitation patterns specific to this vulnerability. 9. Maintain up-to-date backups of survey and poll data to enable recovery in case of data manipulation.
