CVE-2025-63074: 
WordPress vulnerability analysis and mitigation

CVE-2025-63074 is a Local File Inclusion (LFI) vulnerability in the Dream-Theme The7 WordPress theme (plugin slug: dt-the7) caused by improper control of filenames in PHP include/require statements. It affects all versions of The7 prior to 12.8.1.1. The vulnerability was reported by researcher João Pedro S Alcântara (Kinorth) on September 4, 2025, published by Patchstack on October 4, 2025, and assigned a CVSS v3.1 base score of 7.5 (High) (Patchstack).

The root cause is classified as CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program), where user-supplied input is insufficiently sanitized before being passed to PHP file inclusion functions. An authenticated attacker with at least Contributor-level privileges can manipulate the filename parameter to include arbitrary local PHP files from the server's filesystem. Exploitation requires network access and low-privilege authentication, but no user interaction, making it exploitable remotely by any registered WordPress user with Contributor or Developer role (Patchstack).

Successful exploitation allows an attacker to read sensitive local files — such as WordPress configuration files (wp-config.php) containing database credentials — potentially leading to full database compromise. Depending on server configuration, LFI may also be chained with other techniques (e.g., log poisoning) to achieve remote code execution. The confidentiality, integrity, and availability of the affected WordPress site are all at high risk (Patchstack).

No public proof-of-concept exploit code or evidence of active in-the-wild exploitation has been reported at this time. The EPSS score is approximately 0.147%, indicating a low probability of exploitation in the near term. Patchstack classifies the priority as Low, noting it is unlikely to be exploited imminently, though LFI vulnerabilities of this class are noted as being used in mass-exploit campaigns targeting WordPress sites at scale. The vulnerability is not currently listed in the CISA Known Exploited Vulnerabilities (KEV) catalog (Patchstack).

1. Reconnaissance: Identify WordPress sites running the Dream-Theme The7 theme (versions < 12.8.1.1) using tools like WPScan, Shodan, or by inspecting theme metadata in page source.
2. Obtain low-privilege access: Register or obtain credentials for a WordPress account with at least Contributor-level privileges on the target site.
3. Identify vulnerable parameter: Locate the theme functionality that accepts a filename or path parameter passed to a PHP include/require statement — typically exposed through a theme shortcode, widget, or AJAX handler.
4. Craft malicious request: Submit a crafted HTTP request with a manipulated filename parameter pointing to a sensitive local file (e.g., ../../../../wp-config.php) to trigger file inclusion.
5. Extract sensitive data: Review the server response for the contents of the included file, extracting database credentials, secret keys, or other sensitive configuration data.
6. Escalate (optional): Use extracted database credentials to access the WordPress database directly, or chain the LFI with log poisoning to achieve remote code execution (Patchstack).

• Network: Unusual HTTP requests from authenticated low-privilege users containing path traversal sequences (e.g., ../, ..%2F, %2e%2e%2f) in theme-related parameters or AJAX endpoints.
• Logs: WordPress access logs showing requests to theme-specific endpoints with encoded or raw directory traversal strings; repeated 200 responses to requests containing wp-config or other sensitive filenames.
• File System: Unexpected access timestamps on sensitive files such as wp-config.php, PHP session files, or server log files that correlate with suspicious request activity.
• Process: PHP processes reading files outside the expected WordPress theme directory, particularly system files or configuration files, visible in server-side monitoring or audit logs.

The vendor Dream-Theme has released version 12.8.1.1 of The7 theme, which patches this vulnerability. All site administrators running The7 versions prior to 12.8.1.1 should update immediately via the WordPress admin dashboard or by downloading the patched theme from the official source. As a temporary workaround if immediate update is not possible, restrict Contributor-level user registration and review existing Contributor/Developer accounts for unauthorized access. Hosting providers or web developers can also assist with applying the update (Patchstack).
