Summary

CVE-2026-3018 is a high-severity SQL Injection (CWE-89) vulnerability in Wordpress (inferred from references). Its CVSS base score is 7.5 (High).

Operationally, ranked in the top 31.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis

The Newsletters plugin for WordPress is vulnerable to time-based SQL injection via the wpmlsubscriber_id parameter in all versions through 4.13. The flaw stems from insufficient escaping of user-supplied input and the absence of prepared statements on an existing SQL query, allowing arbitrary query manipulation. The issue is tracked as CWE-89 with a CVSS 3.1 score of 7.5.

Unauthenticated remote attackers can supply crafted input to the affected parameter and append additional SQL statements to existing queries. Successful exploitation enables extraction of sensitive information from the WordPress database without requiring authentication or user interaction.

References from the WordPress plugin repository show a changeset addressing the vulnerable code path in newsletters-lite, while the Wordfence advisory links the issue to the specific identifier and parameter. Site operators should apply the available plugin update to eliminate the injection vector.

EPSS remains flat at 0.1757 with no material increase after disclosure.
