The Wpik WordPress Basic Ajax Form plugin suffers from a stored cross-site scripting vulnerability due to improper neutralization of input in the 'dname' parameter. This allows authenticated users with Contributor or higher privileges to inject arbitrary web scripts into pages. These scripts execute in the context of users who access the injected pages, potentially leading to session hijacking or other client-side attacks. The vulnerability affects all versions up to 1.0. There is currently no vendor-provided patch or official remediation available.

An attacker with Contributor-level or higher access can inject persistent malicious scripts that execute in the browsers of users viewing the compromised pages. This can lead to unauthorized actions performed on behalf of users, theft of sensitive information, or other client-side attacks. The vulnerability does not affect availability and requires authenticated access, limiting its scope. No known exploitation in the wild has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Contributor-level access to trusted users only and consider disabling or removing the vulnerable plugin to prevent exploitation.
