The Form Maker by 10Web plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. Specifically, the plugin fails to adequately sanitize and escape the display name of authenticated users when autofilling forms, allowing injection of arbitrary scripts. This affects all versions up to and including 1.15.24. An attacker with subscriber-level privileges or higher can exploit this to execute scripts in the context of other users viewing the injected pages. The CVSS 3.1 base score is 4.4, reflecting network attack vector, high attack complexity, low privileges required, user interaction needed, and partial impact on confidentiality and integrity.

Successful exploitation allows an authenticated user with subscriber-level access or above to inject malicious scripts that execute in the browsers of other users viewing the affected pages. This can lead to partial disclosure of information and integrity impact within the context of the WordPress site. There is no impact on availability. No known exploits in the wild have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict subscriber-level user permissions where possible and monitor for suspicious activity related to form inputs. Avoid autofilling user display names in forms or sanitize inputs manually if feasible.
