CVE-2026-22502 identifies a Local File Inclusion (LFI) vulnerability in the AncoraThemes Mr. Cobbler WordPress theme, specifically in versions up to and including 1.1.9. The vulnerability arises from improper validation and control of filenames used in PHP include or require statements. This flaw allows an attacker to manipulate the input that determines which files are included by the PHP script, potentially enabling the inclusion of arbitrary local files on the web server. Such inclusion can lead to disclosure of sensitive information such as configuration files, source code, or credentials. In some cases, if combined with other vulnerabilities or misconfigurations, it could lead to remote code execution. The vulnerability is classified as a PHP Remote File Inclusion type but is currently identified as Local File Inclusion due to the nature of the flaw. No official patches or updates are currently linked, and no known exploits have been reported in the wild as of the publication date. The vulnerability affects websites running the Mr. Cobbler theme, which is used in WordPress content management systems, making it relevant to a broad range of websites, especially those relying on AncoraThemes products. The lack of a CVSS score suggests that the vulnerability is newly disclosed, and detailed impact metrics have yet to be established. However, the technical nature of the flaw and its potential consequences warrant urgent attention from administrators and developers using the affected theme.

The impact of CVE-2026-22502 can be significant for organizations using the vulnerable Mr. Cobbler theme. Successful exploitation can lead to unauthorized disclosure of sensitive files, including configuration files containing database credentials or API keys, which compromises confidentiality. Attackers might also leverage this vulnerability to execute arbitrary code if they can include malicious files or chain this flaw with other vulnerabilities, affecting integrity and availability. This can result in website defacement, data theft, or full server compromise. For organizations relying on their web presence for business operations, such an incident can cause reputational damage, financial loss, and regulatory penalties. The scope is limited to websites using the vulnerable theme, but given WordPress's widespread use, the number of potentially affected sites is non-trivial. The ease of exploitation depends on the ability to control the filename parameter, which is typically accessible via URL parameters or POST data. No authentication is required, increasing the risk of automated exploitation once public proof-of-concept code or exploits become available.

To mitigate CVE-2026-22502, organizations should first check if they are using the AncoraThemes Mr. Cobbler theme version 1.1.9 or earlier and upgrade to a patched version once available. In the absence of an official patch, administrators can apply temporary mitigations such as disabling the vulnerable include functionality or restricting input parameters to allow only safe, predefined filenames using whitelisting. Implementing Web Application Firewall (WAF) rules to detect and block suspicious requests attempting to manipulate include parameters can reduce exploitation risk. Additionally, hardening PHP configurations by disabling allow_url_include and restricting file system permissions to prevent unauthorized file access can limit the impact. Regularly auditing web server logs for unusual access patterns and employing intrusion detection systems can help identify exploitation attempts early. Developers should review and sanitize all user inputs rigorously, avoiding dynamic file inclusion based on user-controlled data. Finally, maintaining regular backups and incident response plans ensures readiness in case of compromise.
