CVE-2026-78294: Geo Mashup Cross-Site Scripting (XSS)

CVE-2026-78294 · Severity: medium · CVSS 6.5 · Published 2026-09-17

Geo Mashup is a WordPress plugin that adds interactive map functionality to websites. This vulnerability allows contributors (users with low-level editing permissions) to inject malicious scripts into the site through a stored XSS flaw. If exploited, an attacker could steal visitor data, hijack user accounts, or deface the website—though successful exploitation requires a privileged user to be tricked into interacting with malicious content.
