The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Exploitation Conditions

Requires only that the target WordPress site has the WP Data Access plugin installed and activated at version 5.5.70 or earlier, with the vulnerable plugin endpoint reachable over the network. CVSS PR:N/UI:N confirms no authentication, no user interaction, and no special non-default configuration is necessary - exploitation works against default installations. Limiting factors: the specific vulnerable parameter and endpoint are not disclosed in the available public data (Patchstack typically withholds technical detail until patch uptake), and the site must of course be running this particular third-party plugin rather than being a stock WordPress installation.

Impact

The CVSS vector AV:N/AC:L/PR:N/UI:N indicates trivial remote exploitation with no authentication and no user interaction, which is unusually severe for a WordPress plugin flaw and justifies prioritization. The S:C/C:H/I:N/A:L impact profile indicates primary value to attackers is data exfiltration (including potential password hashes and secrets) rather than data tampering, with limited availability impact. Patchstack reporting lends credibility to the finding, but no EPSS score, KEV listing, or public POC was provided - meaning real-world exploitation likelihood is currently unmeasured; given WordPress plugin SQLi flaws are routinely weaponized by automated scanners within days of disclosure, defenders should treat this as high priority despite the absence of confirmed in-the-wild activity.

Exploit ScenarioDerived

An attacker scans WordPress sites for the WP Data Access plugin and sends a crafted HTTP request containing a malicious SQL payload to a vulnerable plugin endpoint, with no login or user interaction required. The injected query extracts password hashes from wp_users and secret keys from wp_options, enabling offline cracking and follow-on takeover of administrator accounts. No public POC was identified at time of analysis, but the CWE-89 class and trivial CVSS attack complexity make rapid exploit weaponization realistic once technical details are published.

AnalysisAIv1 – Jun 15, 2026

Unauthenticated SQL injection in the WP Data Access WordPress plugin (versions <= 5.5.70) allows remote attackers to inject arbitrary SQL through the plugin's interfaces without authentication. The high CVSS 9.3 score reflects a scope change (S:C) that lets the injection reach beyond the vulnerable component, exposing the entire WordPress database to confidentiality compromise. No public exploit identified at time of analysis, and the vulnerability is not currently listed in CISA KEV.

RemediationAI

Upstream fix available per Patchstack advisory; released patched version not independently confirmed in the provided data, but administrators should upgrade WP Data Access to the latest version above 5.5.70 via the WordPress plugin dashboard and consult the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/wp-data-access/vulnerability/wordpress-wp-data-access-plugin-5-5-70-sql-injection-vulnerability for the exact fixed release. If immediate patching is not possible, deactivate the WP Data Access plugin entirely (acceptable trade-off for sites not actively using its data management features) or place the WordPress admin and plugin endpoints behind a Web Application Firewall such as Patchstack, Wordfence, or Cloudflare with SQLi signature rules enabled (side effect: may produce false positives on legitimate queries containing SQL keywords). Additionally, restrict database user privileges so the WordPress DB account cannot read MySQL system tables or execute FILE operations, limiting the blast radius of successful injection.

Technical ContextAI · show details

WP Data Access is a third-party WordPress plugin (CPE: passionate_programmer_peter:wp_data_access) that provides data management, table editing, and reporting features against the WordPress database. The root cause is CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), meaning user-controlled input is concatenated into SQL statements without proper parameterization or escaping. Because the plugin operates directly against the WordPress MySQL/MariaDB backend with the privileges of the WordPress database user, injection here yields access to all WordPress tables including wp_users and wp_options.

DescriptionCVE.org

Unauthenticated SQL Injection in WP Data Access <= 5.5.70 versions.

Executive ViewAI

Why It Matters

The WP Data Access WordPress plugin (versions 5.5.70 and earlier) contains a critical unauthenticated SQL injection vulnerability enabling unrestricted access to the entire WordPress database. No public exploit has been identified at time of analysis; however, the vulnerability's lack of authentication requirement and broad scope make it one of the highest-impact database exposure risks, affecting any organization using this widely-deployed plugin.

Business Impact: Severe
Compensating Controls

Disable the plugin immediately or restrict to authenticated administrator access; Web Application Firewall rules blocking SQL injection patterns; real-time database query monitoring and alerting; network segmentation limiting database access; encrypted daily database backups; comprehensive audit logging of database modifications; migration to actively-maintained alternative plugins.
