Summary

CVE-2026-17044 is an unauthenticated SQL injection vulnerability in the Iptanus File Upload (WordPress File Upload) plugin for WordPress. The plugin fails to properly sanitize and escape the uniqueuploadid parameter before using it in a SQL statement, allowing unauthenticated attackers to inject arbitrary SQL. The issue carries a High severity rating and affects all plugin versions prior to 5.1.8.

Technical details

  • Root cause: the plugin does not sanitize/escape the uniqueuploadid parameter before incorporating it into a SQL query.
  • Trigger: an unauthenticated request supplying a crafted uniqueuploadid value to the vulnerable plugin endpoint.
  • Attack vector: network-based, no authentication or user interaction required, low attack complexity.
  • Impact: unauthorized read access to database contents (high confidentiality impact); no reported impact on integrity or availability per the CVSS vector.

Affected software

  • Iptanus File Upload (WordPress File Upload) plugin for WordPress, versions prior to 5.1.8.

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: upgrade the Iptanus File Upload (WordPress File Upload) plugin to version 5.1.8 or later.
  • If patching is not immediately possible: restrict or disable public access to the plugin’s upload-handling endpoints, and monitor/filter requests containing anomalous uniqueuploadid values via a web application firewall.

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.
