CVE-2026-73378

The vulnerability allows unauthenticated cross-site scripting (XSS) in the Contact Form plugin by Supsystic for versions prior to 1.10.0, potentially enabling attackers to inject malicious scripts into web pages viewed by users. This could lead to session hijacking, data theft, or defacement of the website. Organizations using affected versions of the plugin should prioritize patching to mitigate the risk of exploitation.
