CVE-2025-60046: 
WordPress vulnerability analysis and mitigation

CVE-2025-60046 is a Local File Inclusion (LFI) vulnerability in the HeartStar WordPress theme developed by Axiomthemes. It stems from improper control of filenames in PHP include/require statements, allowing unauthenticated remote attackers to include arbitrary local files. All versions of the HeartStar theme up to and including 1.0.14 are affected. The vulnerability was reported by security researcher "Bonds" on July 23, 2025, and published by Patchstack on August 22, 2025. It carries a CVSS v3.1 base score of 8.1 (High) (Patchstack).

The vulnerability is classified under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program), which occurs when user-supplied input is used to construct file paths passed to PHP's include or require statements without adequate sanitization or validation. An unauthenticated attacker can craft a malicious HTTP request that manipulates the file path parameter, causing the server to include arbitrary local files and return their contents. The attack vector is network-based with high attack complexity and requires no privileges or user interaction, consistent with CAPEC-193 (PHP Remote File Inclusion) patterns (Patchstack).

Successful exploitation allows an attacker to read sensitive files on the server, including configuration files containing database credentials (e.g., WordPress wp-config.php), system files, and other confidential data. This can lead to complete database takeover, exposure of authentication secrets, and potential escalation to remote code execution if the attacker can chain the LFI with file upload or log poisoning techniques. The confidentiality, integrity, and availability of the affected WordPress installation are all rated as High impact (Patchstack).

As of the time of publication, there is no public proof-of-concept exploit code and no evidence of active in-the-wild exploitation (Patchstack). The EPSS score is approximately 0.053%, indicating a currently low probability of exploitation in the near term. No threat actor attribution has been reported, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. However, Patchstack classifies it as high priority and notes that vulnerabilities of this type are commonly used in mass-exploit campaigns targeting WordPress sites at scale.

1. Reconnaissance: Identify WordPress sites using the HeartStar theme (version ≤ 1.0.14) via web crawlers, Shodan, WPScan, or similar tools that enumerate WordPress theme metadata.
2. Identify vulnerable parameter: Analyze the theme's PHP source code or observed HTTP requests to locate parameters passed to include/require statements without sanitization.
3. Craft malicious request: Send an unauthenticated HTTP GET or POST request to the vulnerable endpoint with a manipulated file path parameter (e.g., ?file=../../../../wp-config.php or similar path traversal sequences).
4. Extract sensitive data: Review the server's response for the contents of the included file — such as wp-config.php containing database credentials, salts, and keys.
5. Escalate access: Use extracted credentials to access the WordPress database directly, log in to the admin panel, or chain with other vulnerabilities (e.g., log poisoning) to achieve remote code execution (Patchstack).

• Network: Unusual HTTP requests containing path traversal sequences (e.g., ../, ..%2F, ....//) in query parameters or POST body targeting HeartStar theme endpoints; unexpected outbound connections from the web server.
• Logs: Web server access logs showing requests with encoded or plain path traversal strings to theme-related PHP files; repeated 200 responses to requests with suspicious file path parameters.
• File System: Unexpected access timestamps on sensitive files such as wp-config.php, /etc/passwd, or PHP session files; presence of web shells in the theme directory.
• Process: Unusual PHP processes spawning child processes (e.g., bash, curl, wget) from the web server user account.

As of the publication date, no official patch from Axiomthemes is available for the HeartStar theme beyond version 1.0.14. Site owners should upgrade to any version released after 1.0.14 if one becomes available, or consider replacing the theme with a supported alternative. Patchstack has issued a virtual patching/mitigation rule for its subscribers to block exploitation attempts in the interim. Additional hardening steps include implementing a Web Application Firewall (WAF) with rules to block path traversal patterns, enforcing strict input validation and allowlisting for file inclusion paths at the application or server level, and reviewing server configurations to restrict PHP file access outside the web root (Patchstack).
