JetSmartFilters: Stored cross-site scripting
JetSmartFilters <= 3.8.6.1 permits stored cross-site scripting: attacker-controlled content is persisted and later rendered without sufficient neutralization, allowing script to execute in a viewer’s browser under the affected site’s origin. The supplied CVSS vector requires a low-privilege authenticated attacker and victim interaction, but the export does not identify the minimum WordPress role, editable field, endpoint or rendering function. The resulting access is bounded by the viewing user’s browser context; an administrator victim or complete site takeover is not established.

3.8.6.2- Published
- Oct 26, 2026
This CVE was published Oct 26, 2026 and is one of 8 known issues for this plugin.
Update, patch or deactivate.
Update JetSmartFilters to 3.8.6.2 or later. The application fix must neutralize stored input and escape it for its final HTML, attribute or script context. Inspect content editable by the affected low-privilege users and remove injected markup; do not rely on output handling that turns encoded content back into executable markup.
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.
