CVE-2026-15735 is a stored cross-site scripting vulnerability in the Contact Form to Any API WordPress plugin by itpathsolutions. Versions up to and including 3.0.6 are affected. Authenticated attackers with contributor-level privileges or above can inject arbitrary web scripts through the 'cf7anyapi_form_field' post meta due to improper neutralization of input during web page generation. The vulnerability allows script execution in the context of users visiting the injected pages. The CVSS 3.1 base score is 6.4, reflecting medium severity with network attack vector, low attack complexity, and requiring privileges but no user interaction.

Successful exploitation enables an attacker with contributor-level access or higher to execute arbitrary scripts in the browsers of users who view the compromised pages. This can lead to theft of user credentials, session hijacking, or other malicious actions performed with the victim's privileges. The vulnerability does not impact availability but compromises confidentiality and integrity to a limited extent.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict contributor-level access to trusted users only and consider disabling or limiting use of the Contact Form to Any API plugin. Monitor vendor channels for updates and apply official patches once released.
