Deeper analysis

CVE-2026-28136 is an Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability, classified under CWE-89, in the VeronaLabs WP SMS (wp-sms) WordPress plugin. This issue affects the plugin from unknown initial versions through version 6.9.12 inclusive. Published on 2026-02-26, it carries a CVSS v3.1 base score of 7.6 (AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:L), reflecting high severity primarily due to its network accessibility and potential for significant confidentiality impact.

High-privileged users (PR:H), such as administrators, can exploit this vulnerability remotely over the network (AV:N) with low complexity (AC:L) and no user interaction (UI:N). Exploitation enables SQL injection attacks that achieve high confidentiality impact (C:H) by extracting sensitive data from the database, with a changed scope (S:C) amplifying effects across the system, low availability disruption (A:L), and no integrity impact (I:N).

The Patchstack advisory at https://patchstack.com/database/Wordpress/Plugin/wp-sms/vulnerability/wordpress-wp-sms-plugin-6-9-12-sql-injection-vulnerability?_s_id=cve details this SQL injection vulnerability in WP SMS version 6.9.12 and serves as the primary reference for security practitioners seeking further technical analysis and mitigation recommendations.
