CVE-2025-53442: 
WordPress vulnerability analysis and mitigation

CVE-2025-53442 is a PHP Local File Inclusion (LFI) vulnerability in the Rentic WordPress theme by Axiomthemes, classified under CWE-98 (Improper Control of Filename for Include/Require Statement). It affects all versions of the Rentic theme up to and including version 1.1. The vulnerability was reported by security researcher "Bonds" on August 3, 2025, and published by Patchstack on September 2, 2025. It carries a CVSS v3.1 base score of 8.1 (High) (Patchstack).

The root cause is improper control of filenames used in PHP include/require statements (CWE-98), which allows an attacker to manipulate file path parameters and cause the application to include arbitrary local files. No authentication is required to trigger the vulnerability, and exploitation requires high attack complexity (e.g., specific server configurations or chained conditions). The vulnerability is classified under OWASP Top 10 A3: Injection and maps to CAPEC-193 (PHP Remote File Inclusion). No public proof-of-concept code has been disclosed as of the time of reporting (Patchstack).

Successful exploitation allows an unauthenticated attacker to read sensitive local files on the server, including configuration files containing database credentials, which could lead to complete database takeover. In certain configurations, the vulnerability may also enable execution of arbitrary PHP code, resulting in full compromise of the affected WordPress site's confidentiality, integrity, and availability. The scope is limited to the affected server, but credential exposure could facilitate lateral movement to backend databases or other connected systems (Patchstack).

There is no public proof-of-concept exploit available, and no evidence of in-the-wild exploitation has been reported as of the publication date. The EPSS score is approximately 0.115%, indicating a low current probability of exploitation. No threat actor attribution has been made, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. However, Patchstack rates it as high priority, noting that vulnerabilities of this class are frequently used in mass-exploit campaigns targeting WordPress sites (Patchstack).

As of the time of disclosure, no official patch from the theme developer (Axiomthemes) is available for the Rentic theme. Patchstack has issued a virtual patching/mitigation rule for its subscribers to block exploitation attempts until an official fix is released. Recommended actions include: upgrading to the latest available version of the Rentic theme if a patch becomes available, implementing strict input validation for file inclusion parameters, using allowlists for permitted file paths, deploying a Web Application Firewall (WAF) to detect and block LFI attempts, and applying the principle of least privilege to the web server process (Patchstack).

Patchstack, the assigning CNA, has flagged this vulnerability as high priority and noted that LFI vulnerabilities of this type are commonly leveraged in mass-exploit campaigns against WordPress sites. No notable independent researcher commentary or significant media coverage has been identified beyond the Patchstack advisory (Patchstack).
