Summary

CVE-2026-66649 is an unauthenticated SQL injection vulnerability in the Directory Pro WordPress plugin, developed by e-plugins, affecting all versions up to and including 2.5.8. The flaw allows a remote, unauthenticated attacker to inject SQL commands into the plugin’s database queries. It carries a CVSS v3.1 base score of 9.3 (Critical).

Technical details

  • Root cause: Improper neutralization of special elements used in SQL commands (CWE-89), allowing attacker-controlled input to reach database queries without sufficient sanitization.
  • Trigger conditions: No authentication or user interaction is required to exploit the flaw.
  • Attack vector: Network-accessible; low attack complexity; classified as blind SQL injection (CAPEC-7).
  • Impact: High confidentiality impact (unauthorized access to database contents) and low availability impact; integrity is not affected.

Affected software

  • Directory Pro (WordPress plugin) — versions up to and including 2.5.8

Severity

  • CVSS v3.1 Base Score: 9.3 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L

Mitigation and recommended actions

  • Immediate: Upgrade Directory Pro to a version released after 2.5.8 that addresses this SQL injection issue.
  • If no patch is available: Temporarily deactivate the Directory Pro plugin on affected WordPress sites, or restrict access to the plugin’s public-facing endpoints via a web application firewall until an update is applied. Monitor database and web server logs for anomalous query patterns indicative of SQL injection attempts.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
