CVE-2026-53741: Quantumcloud Simple Link Directory

Medium severity, CVSS 5.4. EPSS: 0.2% chance of exploitation in the next 30 days.

Simple Link Directory through 9.0.4 interpolates the sld_no_results_found option into a JavaScript string literal without encoding. Because sanitize_text_field leaves quotes intact, a stored payload breaks out of the string and runs script for every page visitor.

Affected products

• Quantumcloud Simple Link Directory: up to and including 9.0.4
