Security readout for executives and security teams
Plain-English summary
This is a WordPress/WooCommerce plugin flaw that can let a logged-in Shop Manager or higher-privileged user extract sensitive database information through a shipping-city setting. It is not described as anonymously exploitable. Business urgency is moderate: prioritize sites where many staff have Shop Manager access or where account compromise is a realistic concern.
Executive priority
Treat as a moderate-priority remediation item. It is not anonymous or KEV-listed, but it can expose database information if a privileged account is misused or compromised. Focus first on ecommerce sites with sensitive customer data and broad Shop Manager access.
Technical view
CVE-2026-0678 is a time-based SQL injection in the Flat Shipping Rate by City for WooCommerce / Shipping Rates by City for WooCommerce plugin through version 1.0.3. The issue is in the 'cities' parameter, caused by insufficient escaping and query preparation. CVSS 3.1 is 4.9, with high confidentiality impact and no integrity or availability impact listed.
Likely exposure
Exposure is limited to WordPress/WooCommerce sites using the affected plugin versions up to and including 1.0.3. The attacker must already have Shop Manager-level access or higher, so compromised staff accounts, over-permissioned users, or malicious insiders are the main concern.
Exploitation context
The provided sources do not report active exploitation, and the CVE is not marked as KEV. Exploitation requires authenticated high-privilege access and targets database confidentiality. Time-based SQL injection may be slower but can still expose sensitive data if abused.
Researcher notes
Sources identify CWE-89 and reference the vulnerable code location around shipping-method-class.php line 154. The bundle’s affected-version metadata is not fully clear, while the description states versions up to 1.0.3. No fixed version is provided in the supplied sources, so remediation should be verified with vendor guidance.
Mitigation direction
- Inventory WordPress sites for this WooCommerce shipping-rate plugin.
- Identify installations running versions up to and including 1.0.3.
- Check vendor or WordPress plugin guidance for an updated or fixed release.
- If no fix is available, consider disabling the plugin pending vendor guidance.
- Restrict Shop Manager access to trusted users only.
- Review privileged WordPress accounts for compromise or unnecessary permissions.
Validation and detection
- Confirm plugin name and version on each WooCommerce site.
- List users with Shop Manager, Administrator, or equivalent roles.
- Review logs for unusual authenticated access to shipping-rate settings.
- Check Wordfence or vendor advisories for current remediation status.
- Document whether affected sites are internet-facing and business-critical.
