The Form Maker by 10Web plugin for WordPress suffers from a reflected cross-site scripting vulnerability due to the use of add_query_arg without proper escaping of URL parameters in all versions up to 1.15.30. This allows unauthenticated attackers to inject malicious scripts that execute in the context of a victim's browser when they click on a manipulated link. The vulnerability is classified under CWE-79 and has a CVSS 3.1 base score of 6.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction needed, and impacts on confidentiality and integrity with scope change.

Successful exploitation can lead to the execution of arbitrary scripts in the context of the victim's browser, potentially allowing theft of sensitive information or manipulation of site content. The impact affects confidentiality and integrity but does not affect availability. Since the attack requires user interaction, the risk is moderated but still significant for targeted phishing or social engineering attacks.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should avoid clicking on suspicious links related to the affected plugin and consider disabling or replacing the plugin if possible. Monitor vendor channels for updates and apply patches promptly once available.
