What to do

Update, patch or deactivate.

No fixed release is identified. Update Smash Balloon Social Photo Feed – Easy Social Feeds Plugin when a release after 6.11.3 becomes available; until then, disable and remove it when the site's risk warrants. The official upstream changelog lists version 6.12.0, which is newer than the published affected range. Its changelog does not clearly confirm this specific fix, so it is not counted as a known-safe release.

No confirmed safe version is listed. Consider a vendor-supported patch or temporarily restricting the affected functionality while you assess the risk.

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.

Source record

Technical description

The Smash Balloon Social Photo Feed – Easy Social Feeds Plugin plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via REQUEST_URI Query String in all versions up to, and including, 6.11.3 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
