CVE-2026-15399 wpmart CVE debrief

Who should care

Defenders responsible for WordPress installations with the Animated Number Counters plugin, especially those with editor-level access, should assess exposure and prioritize patching or mitigating this vulnerability.

Why it matters

CVE-2026-15399 is a SQL Injection vulnerability in the Animated Number Counters plugin for WordPress, allowing authenticated attackers with editor-level access to extract sensitive information from the database. Defenders should prioritize patching, restrict editor-level access, and monitor database queries for suspicious activity.

• Potential data breaches due to sensitive information extraction
• Increased risk of lateral movement within the network
• Potential disruption of database operations
• Need for verification of patch deployment and vulnerability remediation

Technical summary

The Animated Number Counters plugin for WordPress is vulnerable to SQL Injection via the 'counterid' parameter in all versions up to, and including, 3.0. This makes it possible for authenticated attackers, with editor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The vulnerability is caused by insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. The write path correctly uses $wpdb->prepare(), but that protection is not carried forward to the read path, where the retrieved value is concatenated unsanitized into unprepared queries in both a

Defensive priority

Defenders should prioritize patching or mitigating this vulnerability, especially in environments where editor-level access is common.

Recommended defensive actions

• Patch the Animated Number Counters plugin to version greater than 3.0
• Restrict editor-level access to only trusted users
• Monitor database queries for suspicious activity
• Consider implementing additional security measures such as web application firewalls
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.

Evidence notes

The vulnerability is caused by insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. The write path correctly uses $wpdb->prepare(), but that protection is not carried forward to the read path.
