If-So Dynamic Content: Reflected XSS in an unauthenticated AJAX response
The If-So Dynamic Content WordPress plugin before 1.10.2 does not escape a request-supplied value before reflecting it in an unauthenticated AJAX response that is served as HTML, allowing attackers to execute arbitrary JavaScript in the browser of a visitor who opens a crafted link. The authoritative export does not name the request parameter or handler beyond the affected feature described above. The authoritative export identifies the fixed release as 1.10.2.

This CVE was published Oct 01, 2026 and is one of 10 known issues for this plugin.
Update, patch or deactivate.
Update If-So Dynamic Content to 1.10.2 or a later supported release. An application-level fix should validate stored/request input and escape it for the final HTML, attribute, URL or DOM context. Remove persisted malicious content where storage is involved.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
