LightStart - Maintenance Mode, Coming Soon and Landing Page Builder v1.6.5

Scan ID: SCAN-WP-MAINTENANCE-MODE-7oX0gP • Hash: 8e14f4de

Security Simulation Profile Active

E-ComGuard was unable to download the source files for LightStart - Maintenance Mode, Coming Soon and Landing Page Builder (v1.6.5) from WordPress.org or GitHub. This typically happens when the slug identifier is custom-branded, the repository tag does not exist, or the files are restricted.

To prevent blocking your queue pipeline, the hybrid scanner fell back to generating realistic vulnerability models based on typical security risks detected in equivalent components.
