CVE-2025-14393 identifies a stored Cross-Site Scripting (XSS) vulnerability in the Wpik WordPress Basic Ajax Form plugin, maintained by awanhrp. The vulnerability arises from improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of the 'dname' parameter in all plugin versions up to and including 1.0. An attacker with authenticated access at the Contributor level or above can inject arbitrary JavaScript code that is persistently stored and executed in the context of any user who visits the affected page. This persistent XSS flaw can lead to a range of attacks including session hijacking, privilege escalation, unauthorized actions on behalf of users, or distribution of malware. The vulnerability is remotely exploitable over the network without user interaction but requires authenticated access, which limits the attack surface to users with some level of trust in the system. The CVSS 3.1 base score is 6.4, reflecting medium severity with low attack complexity and partial impact on confidentiality and integrity but no impact on availability. No patches or official fixes are currently linked, and no known exploits are reported in the wild. The vulnerability is classified under CWE-79, highlighting the failure to properly sanitize inputs before rendering them in web pages. Given the widespread use of WordPress and the popularity of form plugins, this vulnerability poses a tangible risk to websites that have installed and activated this specific plugin version.

For European organizations, this vulnerability can lead to significant security risks including unauthorized access to user sessions, data theft, and potential defacement or manipulation of website content. Organizations relying on WordPress for their web presence and using the Wpik WordPress Basic Ajax Form plugin are at risk of attackers exploiting contributor-level accounts to inject malicious scripts. This can compromise the confidentiality and integrity of user data and organizational information. The persistent nature of the XSS means that any user visiting the infected pages could be affected, potentially leading to widespread compromise. This is particularly concerning for organizations handling sensitive customer data or providing critical services online. Additionally, reputational damage and regulatory compliance issues (such as GDPR) may arise if personal data is exposed or manipulated through this vulnerability. The requirement for authenticated access somewhat limits the threat to insiders or compromised accounts, but this does not eliminate the risk, especially in environments with many contributors or weak access controls.

European organizations should immediately audit their WordPress installations to identify the presence of the Wpik WordPress Basic Ajax Form plugin and verify the version in use. Since no official patch is currently linked, organizations should consider temporarily disabling or uninstalling the plugin until a secure update is released. Implement strict access controls to limit Contributor-level privileges only to trusted users and regularly review user roles and permissions. Employ Web Application Firewalls (WAFs) with custom rules to detect and block malicious payloads targeting the 'dname' parameter. Enable Content Security Policy (CSP) headers to reduce the impact of potential XSS attacks by restricting script execution sources. Conduct regular security training for contributors to recognize and avoid unsafe input practices. Monitor logs for unusual activity related to form submissions or script injections. Finally, stay updated with vendor advisories for any forthcoming patches or mitigations and apply them promptly once available.
