Summary

CVE-2025-2221 is a high-severity SQL Injection (CWE-89) vulnerability in Wpcom Wpcom Member. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 4.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

The WPCOM Member plugin for WordPress is vulnerable to time-based SQL injection via the user_phone parameter in all versions through 1.7.6. The flaw stems from insufficient escaping of user-supplied input and the absence of prepared statements in the existing SQL query, allowing arbitrary SQL to be appended.

Unauthenticated attackers can exploit the issue over the network to extract sensitive information from the database. The vulnerability carries a CVSS 3.1 score of 7.5 with a vector indicating no required privileges or user interaction.

References to the plugin source and a subsequent changeset indicate that a fix was implemented after version 1.7.6. The EPSS score rose materially from lower values to a peak of 0.6204 on 2026-04-16 before receding to the current 0.2042, signaling increased exploitation interest after disclosure.
