CVE-2026-27341 is a Local File Inclusion (LFI) vulnerability found in the Mikado-Themes TopScorer Sports WordPress theme, specifically in versions up to 1.2. The vulnerability arises from improper control over the filename used in PHP include or require statements, which allows an attacker to manipulate the file path parameter. This improper validation or sanitization can lead to the inclusion of unintended local files on the web server. LFI vulnerabilities can be leveraged to read sensitive files such as configuration files, password files, or other data stored on the server, potentially disclosing credentials or other sensitive information. In some cases, LFI can be escalated to remote code execution if the attacker can upload malicious files or if log files can be included. The vulnerability is specific to the TopScorer theme, which is a WordPress theme designed for sports-related websites. No patch links or fixes are currently indicated, and no known exploits are reported in the wild. The vulnerability was reserved and published in early 2026, and no CVSS score has been assigned yet. The lack of a CVSS score requires an expert severity assessment based on the nature of the vulnerability and its potential impact. The vulnerability requires the attacker to influence the filename parameter, which may require some level of user interaction or access to the application interface. However, once exploited, it can compromise confidentiality and integrity of the affected system.

The impact of CVE-2026-27341 can be significant for organizations using the vulnerable TopScorer WordPress theme. Successful exploitation can lead to unauthorized disclosure of sensitive files, including configuration files containing database credentials, API keys, or other secrets. This can facilitate further attacks such as privilege escalation, data theft, or website defacement. In some scenarios, attackers might leverage LFI to execute arbitrary code if they can include files containing malicious payloads, leading to full system compromise. The vulnerability undermines the confidentiality and integrity of the affected web server and potentially the entire hosting environment. Organizations relying on this theme for public-facing websites risk reputational damage, data breaches, and service disruption. Since WordPress is widely used globally, and themes like TopScorer are popular in niche sports-related sites, the scope of affected systems could be substantial. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits once the vulnerability details become public.

To mitigate CVE-2026-27341, organizations should first check for updates or patches from Mikado-Themes and apply them promptly once available. If no official patch exists, administrators should consider temporarily disabling or replacing the TopScorer theme with a secure alternative. As a practical mitigation, restrict access to the WordPress administration interface to trusted IP addresses to reduce the risk of exploitation. Implement web application firewall (WAF) rules to detect and block attempts to manipulate include/require parameters or suspicious file path traversal patterns. Review and harden PHP configuration settings, such as disabling allow_url_include and restricting open_basedir to limit file inclusion scope. Conduct thorough code audits of the theme to identify and fix improper input validation in include/require statements. Additionally, monitor server logs for unusual file access patterns indicative of LFI attempts. Employ principle of least privilege on the web server file system to minimize the impact of any file inclusion. Finally, educate site administrators about the risks and signs of exploitation to enable rapid response.
