Summary

CVE-2026-73387 is an unauthenticated Local File Inclusion (LFI) vulnerability affecting the Resido WordPress theme, developed by SmartDataSoft, in versions 1.5 and earlier. The flaw stems from improper control of filenames used in PHP include/require statements (CWE-98), allowing an attacker to include arbitrary local files on the server without any authentication. The vulnerability carries a CVSS v3.1 base score of 8.1 (High).

Technical details

  • Root cause: Improper Control of Filename for Include/Require Statement in PHP Program (CWE-98) within the Resido theme’s file inclusion logic.
  • Trigger conditions: No authentication or user interaction is required; an attacker can manipulate input passed to a PHP include/require statement to point to arbitrary local files on the server’s filesystem.
  • Attack vector: Network-based, exploitable remotely over HTTP(S) against any WordPress site running the vulnerable theme.
  • Impact: Successful exploitation can lead to disclosure of sensitive local files, and depending on server configuration, may enable further compromise affecting confidentiality, integrity, and availability of the affected system.

Affected software

  • SmartDataSoft Resido WordPress theme, versions ≤ 1.5

Severity

  • CVSS v3.1 Base Score: 8.1 (High)
  • Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Upgrade the Resido theme to a version newer than 1.5 as soon as a fixed release is made available by the vendor.
  • If no patch is available: Restrict or disable direct access to theme files that process file-inclusion parameters, apply web application firewall (WAF) rules to block path traversal/LFI patterns, and monitor server logs for unusual file access attempts. Consider taking the affected site offline or switching themes until a patched version is confirmed available.

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.
