CVE-2025-12417 is a stored cross-site scripting (XSS) vulnerability identified in the SurveyFunnel – Survey Plugin for WordPress, specifically in all versions up to and including 1.1.5. The vulnerability arises from improper neutralization of input during web page generation (CWE-79), where the plugin fails to adequately sanitize and escape user-supplied attributes passed via the 'surveyfunnel_lite_survey' shortcode. This flaw allows authenticated attackers with contributor-level access or higher to inject arbitrary JavaScript code into pages. Because the injected scripts are stored and rendered whenever any user accesses the compromised page, this can lead to persistent XSS attacks. The impact includes potential session hijacking, unauthorized actions on behalf of users, defacement, or redirection to malicious sites. The CVSS 3.1 base score is 6.4, reflecting medium severity, with an attack vector of network, low attack complexity, requiring privileges (PR:L), no user interaction, and a scope change (S:C) indicating that the vulnerability affects resources beyond the initially vulnerable component. No patches are currently linked, and no known exploits have been reported in the wild. The vulnerability is particularly concerning in multi-user WordPress environments where contributors can add content but are not fully trusted. The plugin’s widespread use in survey and feedback collection on WordPress sites increases the potential attack surface.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of web applications using the SurveyFunnel plugin. Attackers with contributor access can inject malicious scripts that execute in the context of other users, potentially stealing session cookies, performing unauthorized actions, or spreading malware. This can lead to data breaches, reputational damage, and regulatory non-compliance under GDPR if personal data is compromised. The medium CVSS score reflects moderate impact, but the scope change indicates that the vulnerability can affect other components or users beyond the initial contributor. Organizations with collaborative content creation workflows are particularly vulnerable, as contributors often have legitimate access but limited security oversight. The lack of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits once the vulnerability is public. The availability of the plugin across many WordPress sites in Europe means that a broad range of sectors, including education, government, and commerce, could be targeted.

1. Monitor for and apply official patches or updates from the plugin vendor as soon as they become available. 2. Until patches are released, restrict contributor-level access to trusted users only and review existing contributor permissions. 3. Implement web application firewalls (WAFs) with rules to detect and block XSS payloads targeting the 'surveyfunnel_lite_survey' shortcode. 4. Employ additional input validation and output encoding at the application level, especially for user-supplied shortcode attributes. 5. Conduct regular security audits and code reviews of WordPress plugins and themes to detect similar vulnerabilities. 6. Educate content contributors about the risks of injecting untrusted content and enforce strict content submission policies. 7. Use Content Security Policy (CSP) headers to limit the execution of unauthorized scripts on affected sites. 8. Monitor logs for unusual activity or script injection attempts related to the plugin. 9. Consider isolating or disabling the SurveyFunnel plugin if it is not critical to operations until a secure version is available.
