Deeper analysis

CVE-2026-42646 is an Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability, specifically enabling Blind SQL Injection, in the Steve Burge TaxoPress simple-tags WordPress plugin. This issue affects TaxoPress versions from n/a through <= 3.44.0. The vulnerability 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) and is associated with CWE-89.

Exploitation requires high privileges (PR:H), such as those of an authenticated administrator, but is network accessible (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N). Attackers can achieve high confidentiality impact (C:H) with a changed scope (S:C), potentially extracting sensitive data from the database via blind SQL injection techniques, alongside low availability impact (A:L) and no integrity impact (I:N).

The Patchstack advisory (https://patchstack.com/database/Wordpress/Plugin/simple-tags/vulnerability/wordpress-taxopress-plugin-3-44-0-sql-injection-vulnerability?_s_id=cve) documents this SQL injection vulnerability in the WordPress TaxoPress plugin version 3.44.0.

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly mitigates blind SQL injection in TaxoPress by validating and sanitizing user inputs before they are used in SQL commands.

SI-2 Flaw Remediation good match
prevent

Remediates the specific SQL injection flaw in TaxoPress versions through <=3.44.0 by identifying, testing, and applying vendor-provided patches.

SC-7 Boundary Protection partial match
prevent

Provides defense-in-depth against network-accessible SQL injection exploitation via boundary protections like web application firewalls that block malicious payloads.
