Published: April 11, 2026
Official Description
The Paid Memberships Pro WordPress plugin before 2.6.7 does not escape the discount_code in one of its REST route (available to unauthenticated users) before using it in a SQL statement, leading to a SQL injection
Risk Analysis
The Paid Memberships Pro WordPress plugin contains an unauthenticated SQL injection vulnerability in one of its REST routes. This flaw allows attackers to inject malicious SQL statements by manipulating the 'discount_code' parameter. As this vulnerability is in CISA's KEV, it is actively exploited and requires immediate attention.
This vulnerability is actively exploited in the wild. Its unauthenticated nature and remote exploitability make it a high-risk threat.
Upgrade the Paid Memberships Pro WordPress plugin to version 2.6.7 or newer. Ensure all REST API endpoints are properly secured with input validation and parameterized queries.
Technical Analysis
CVE-2021-25114 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2021-25114 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
