CVE-2026-22415 is a Local File Inclusion (LFI) vulnerability found in the AncoraThemes The Mounty WordPress theme, specifically affecting versions up to 1.1. The vulnerability arises from improper control over the filename parameter used in PHP include or require statements. This flaw allows an attacker to manipulate the input controlling which file is included, enabling the inclusion of arbitrary local files on the server. Such an attack can lead to disclosure of sensitive files (e.g., configuration files, password files), execution of malicious PHP code if an attacker can upload files, or even full system compromise depending on server configuration. The vulnerability is classified as a PHP Remote File Inclusion type but is technically a Local File Inclusion since it involves local files. No CVSS score has been assigned yet, and no known exploits have been reported in the wild. The vulnerability was reserved in early January 2026 and published in March 2026. The lack of official patches or mitigation guidance from AncoraThemes increases the risk for users of this theme. Exploitation typically requires sending crafted HTTP requests that manipulate the vulnerable parameter, which does not require authentication but may require knowledge of the vulnerable endpoint. The vulnerability affects WordPress sites using The Mounty theme, which is used primarily by small to medium-sized businesses and blogs. The absence of patch links suggests users must monitor vendor updates closely or apply manual mitigations. This vulnerability is significant because WordPress is a widely used CMS, and themes are a common attack vector. Attackers exploiting this flaw could gain unauthorized access to server files, leading to data breaches or further exploitation.

The impact of CVE-2026-22415 can be severe for organizations running WordPress sites with The Mounty theme. Successful exploitation allows attackers to read sensitive files on the server, such as configuration files containing database credentials, API keys, or other secrets. This can lead to data breaches, unauthorized access to backend systems, and potential lateral movement within the network. If attackers can upload files or leverage other vulnerabilities, they may execute arbitrary code, resulting in full server compromise. This can disrupt website availability, damage organizational reputation, and lead to regulatory compliance violations. Since WordPress powers a significant portion of the web, including e-commerce, government, and enterprise sites, the scope of affected systems is broad. The vulnerability does not require authentication, increasing the attack surface, and can be exploited remotely via crafted web requests. Organizations with public-facing WordPress sites using this theme are at particular risk. The lack of known exploits currently reduces immediate risk but also means attackers may develop exploits soon after disclosure. Without timely patching or mitigation, the vulnerability could be leveraged in targeted or opportunistic attacks, especially against less-secure or outdated WordPress deployments.

1. Monitor AncoraThemes official channels for patches or updates addressing CVE-2026-22415 and apply them promptly once available. 2. In the absence of official patches, implement strict input validation and sanitization on any parameters controlling file inclusion to prevent manipulation. 3. Configure the web server and PHP environment to disable dangerous functions such as allow_url_include and restrict include paths using open_basedir to limit file inclusion to trusted directories. 4. Employ a Web Application Firewall (WAF) with rules designed to detect and block attempts to exploit file inclusion vulnerabilities, including suspicious URL patterns or parameter values. 5. Conduct code reviews and audits of the theme’s PHP files to identify and remediate unsafe include/require statements. 6. Limit file upload capabilities and ensure uploaded files are stored outside the web root or are sanitized to prevent code execution. 7. Regularly back up website data and configurations to enable recovery in case of compromise. 8. Educate site administrators about the risks of using outdated or unpatched themes and encourage prompt updates. 9. Consider temporarily disabling or replacing The Mounty theme with a secure alternative until a patch is available. 10. Monitor web server logs for unusual access patterns indicative of exploitation attempts.
