PDF Invoices & Packing Slips for WooCommerce v3.8.8

Scan ID: SCAN-WOOCOMMERCE-PDF-INVOICES-PACKING-SLIPS-fsv8EI • Hash: 27a1e0e3

Security Simulation Profile Active

E-ComGuard was unable to download the source files for PDF Invoices & Packing Slips for WooCommerce (v3.8.8) 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.
