Summary

CVE-2026-12983 is an unauthenticated SQL injection vulnerability (CWE-89) in the Dinatur WordPress plugin, affecting all versions through 1.18. The flaw stems from unsanitized user input being incorporated into SQL queries via column-name injection, and the same vulnerable code path also allows unauthenticated database table truncation. The issue carries a CVSS v3.1 base score of 8.6 (High).

Technical details

  • Root cause: The plugin fails to properly sanitize/validate user-supplied input before using it in SQL query construction (column name injection).
  • Trigger conditions: No authentication or user interaction is required; the vulnerable handler can be reached directly over the network.
  • Attack vector: Network (AV:N), low attack complexity, no privileges required.
  • Impact: Attackers can perform SQL injection to disclose data from the site’s database (confidentiality impact: High). The same handler additionally permits unauthenticated truncation of the plugin’s database tables, destroying stored plugin data.

Affected software

  • Dinatur WordPress plugin — versions 0 through 1.18 (all released versions up to and including 1.18)

Severity

  • CVSS v3.1 Base Score: 8.6 (High)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N

Mitigation and recommended actions

  • Immediate: Check for a vendor update to Dinatur beyond version 1.18 and apply it as soon as it is released; no fixed version had been identified in public sources at the time of this writing.
  • If no patch is available: Deactivate and remove the Dinatur plugin from affected WordPress installations until a patched version is released. As a network-level mitigation, block or restrict access to the plugin’s endpoints via a web application firewall, and monitor for anomalous SQL error responses or unexpected data-truncation activity.

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.
