| Severity | CVSS 7.5, High |
|---|---|
| Actively exploited? | No |
| Affected | Wpxpo WowStore β Store Builder & Product Blocks for WooCommerce (0 <= 4.4.3) |
| Fixed in | See vendor advisory |
| Type (CWE) | CWE-89: CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') |
What is CVE-2026-2579?
The WowStore β Store Builder & Product Blocks for WooCommerce plugin for WordPress is vulnerable to SQL Injection via the βsearchβ parameter in all versions up to, and including, 4.4.3 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
In practical terms, a successful attacker gets SQL injection that can read or modify the backing database. There is no confirmed in-the-wild exploitation listed in CISA's KEV catalog at the time of writing, but the CVSS rating still warrants prompt patching.
Am I affected?
You're affected if you run Wpxpo WowStore β Store Builder & Product Blocks for WooCommerce at any version in the Affected row above. Use these probes to find your installed build:
# Confirm the installed version via your package manager
dpkg -l | grep -i wowstore # Debian/Ubuntu
rpm -qa | grep -i wowstore # RHEL/CentOS/Rocky
How to fix CVE-2026-2579
The primary fix is to upgrade to the patched build listed in the Fixed in row above (See vendor advisory). Pick the platform that matches your install and run the commands below.
Linux (Ubuntu / Debian)
# Vendor advisory: https://www.wordfence.com/threat-intel/vulnerabilities/id/bd3ee85a-324d-4991-bffc-db28ce374bbe?source=cve
sudo apt-get update
sudo apt-get install --only-upgrade wowstore---store-builder---product-blocks-for-woocommerce
# Confirm the installed version meets or exceeds <patched-version>
dpkg -s wowstore---store-builder---product-blocks-for-woocommerce | grep ^Version
Linux (RHEL / CentOS / Rocky)
sudo dnf upgrade --security wowstore---store-builder---product-blocks-for-woocommerce -y

If you can't patch immediately
These are runnable hardening commands. They reduce blast radius but they're not a replacement for the vendor patch.
Block obvious SQL injection patterns with a WAF rule
# ModSecurity / OWASP CRS-style rule
SecRule ARGS "@rx (?i)(union(.|\n)+?select|select(.|\n)+?from|insert(.|\n)+?into)" \
"id:900100,phase:2,deny,log,msg:'SQLi pattern blocked'"
How to verify the fix worked
Run the version probe again and confirm the running build matches the Fixed in row above.
# Confirm the running build matches the patched version listed by the vendor
# Example for Linux package installs:
dpkg -l | grep -i "wowstore" # Debian/Ubuntu
rpm -qa | grep -i "wowstore" # RHEL/CentOS/Rocky
Expected output: the package version should meet or exceed the patched build.
Then re-run any vulnerability scanner you used previously and confirm the finding for CVE-2026-2579 has cleared. Sweep your logs for the indicators of compromise listed in the vendor or CISA advisory, especially if the system was internet-reachable during the disclosure window.
Frequently asked questions
Is CVE-2026-2579 being actively exploited?
Not at the time of writing. It is not listed in CISA's Known Exploited Vulnerabilities catalog. That status can change, so monitor the vendor advisory and the KEV catalog if the system is exposed.
How severe is CVE-2026-2579?
CVSS rates it 7.5 (High). Use that score to set your patch priority next to the other items in your queue.
Do I have to take WowStore β Store Builder & Product Blocks for WooCommerce offline to apply the patch?
It depends on the deployment. High-availability or clustered installs can usually patch one node at a time with no full outage. Standalone installs typically need a short restart. Always follow the vendor's documented upgrade steps.
What if my vulnerability scanner still flags CVE-2026-2579 after I patch?
Re-run the scan after a service restart, then confirm the scanner's plugin set is up to date. Some scanners detect by banner version only and lag the official fix metadata by a release.
