CVE-2025-68066: 
WordPress vulnerability analysis and mitigation

CVE-2025-68066 is a Local File Inclusion (LFI) vulnerability in the PenciDesign Soledad WordPress theme, classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). It affects all versions of the Soledad theme up to and including 8.7.0. The vulnerability was reported by researcher João Pedro S Alcântara (Kinorth) on September 28, 2025, and published by Patchstack on October 28, 2025, with CVE assignment on December 16, 2025. It carries a CVSS v3.1 base score of 7.5 (High) (Patchstack).

The vulnerability stems from improper validation of filename parameters used in PHP include/require statements within the Soledad theme (CWE-98), enabling PHP Local File Inclusion. An authenticated attacker with at least Contributor-level privileges can manipulate file path inputs to force the server to include arbitrary local files. The attack is network-based but requires high complexity and low-privilege authentication, limiting opportunistic exploitation. No public proof-of-concept code has been identified at this time (Patchstack).

Successful exploitation allows an attacker to read arbitrary local files on the web server, potentially exposing sensitive configuration files such as wp-config.php, which contains database credentials. This could lead to complete database compromise, credential theft, and further lateral movement within the hosting environment. Confidentiality, integrity, and availability are all rated as High impact in the CVSS scoring (Patchstack).

No active in-the-wild exploitation has been reported, and no public exploit code is currently known. The EPSS score is approximately 0.127%, indicating a low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Patchstack classifies this as low priority, noting it is unlikely to be exploited despite being theoretically usable in mass-exploit campaigns targeting WordPress themes (Patchstack).

1. Reconnaissance: Identify WordPress sites using the Soledad theme version ≤ 8.7.0 via tools like WPScan or Shodan, searching for theme-specific fingerprints in page source or HTTP headers.
2. Obtain low-privilege access: Register or obtain a Contributor-level (or higher) WordPress account on the target site, as the vulnerability requires authenticated access.
3. Identify vulnerable parameter: Locate the theme functionality that accepts a filename or template path parameter susceptible to path traversal (e.g., within post/page editing or theme shortcode functionality).
4. Craft LFI payload: Submit a crafted request with a path traversal sequence (e.g., ../../../../wp-config.php) in the vulnerable filename parameter to force inclusion of a sensitive local file.
5. Extract sensitive data: Review the server response for the contents of the included file, such as database credentials from wp-config.php, and use those credentials for further access or lateral movement (Patchstack).

• Logs: WordPress access logs showing authenticated POST or GET requests with path traversal sequences (e.g., ../, ..%2F, ....//) in parameters associated with Soledad theme functionality.
• Logs: PHP error logs referencing unexpected file inclusion attempts or include/require failures for files outside the theme directory.
• Network: Unusual outbound connections from the web server following authenticated requests, potentially indicating secondary payload delivery.
• File System: Unexpected access timestamps on sensitive files such as wp-config.php or /etc/passwd correlating with suspicious web requests.

As of the time of publication, no official patched version of the Soledad theme has been released by PenciDesign. Site administrators should monitor the theme's official update channel and apply any available patch immediately upon release. As a workaround, restrict Contributor-level user registrations and permissions on the WordPress site to reduce the attack surface. Consider deploying a Web Application Firewall (WAF) with rules targeting LFI patterns to provide interim protection (Patchstack).

Patchstack, which discovered and disclosed the vulnerability, classifies it as low priority with limited likelihood of exploitation. The vulnerability was detected by Qualys (detection ID 531009) and included in their March 2026 application security detections publication. No significant vendor statements from PenciDesign or broader media coverage have been identified.
