Component: Simple Link Directory
Plugin slug: simple-link-directory
Affected: <= 9.0.4
Safe version: See mitigation notes
Published: Jun 10, 2026
Weakness: CWE-79 — Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

This CVE was published Jun 10, 2026 and is one of 8 known issues for this plugin.

What to do

Update, patch or deactivate.

No fixed release is identified. Update Simple Link Directory when a release after 9.0.4 becomes available; until then, disable and remove it when the site's risk warrants. The official upstream changelog lists version 9.1.4, 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.
