Summary

CVE-2025-58902 is a high-severity unauthenticated Local File Inclusion (LFI) vulnerability in the AncoraThemes Lighthouse WordPress theme, affecting all versions up to and including 1.2.12. Exploitable remotely without any credentials or user interaction, the flaw enables attackers to manipulate server-side file include operations and read arbitrary files from the host server, potentially exposing sensitive configuration data such as database credentials. The vulnerability carries a CVSS v3.1 base score of 8.1 (High).

Technical details

  • Root cause: The theme fails to adequately validate or sanitize user-supplied input before passing it to PHP include/require statements (CWE-98: Improper Control of Filename for Include/Require Statement in PHP Program). This allows an attacker to craft requests that manipulate the filename parameter to reference arbitrary files on the server’s filesystem.
  • Trigger conditions: Exploitation requires network access to the affected WordPress installation and specific server-side conditions consistent with the High Attack Complexity (AC:H) rating in the CVSS vector. No authentication and no user interaction are required.
  • Attack vector: Remote, unauthenticated HTTP/HTTPS request to the vulnerable WordPress site over the network.
  • Impact: Successful exploitation can expose sensitive server-side files — including those containing database credentials — potentially allowing complete database takeover depending on the server configuration. CVSS impact scores are High across Confidentiality, Integrity, and Availability.

Affected software

  • AncoraThemes Lighthouse WordPress Theme, versions <= 1.2.12

Severity

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

Mitigation and recommended actions

  • No official vendor patch has been released by AncoraThemes as of the publication date of this advisory (July 2, 2026).
  • Immediate: If the Lighthouse theme is not required for current site operation, deactivate and remove it until a patched version is made available.
  • If removal is not immediately possible: Apply Web Application Firewall (WAF) rules to detect and block directory traversal and file inclusion patterns targeting the WordPress theme’s endpoints.
  • Additional hardening: Configure PHP’s open_basedir directive to restrict filesystem access to only the directories required by the application, limiting the scope of any potential file inclusion attempt.
  • Monitor the AncoraThemes ThemeForest product page and the official CVE record for patch availability.

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.
