CVE-2026-22494 is a Local File Inclusion (LFI) vulnerability found in the ThemeREX Good Homes WordPress theme, specifically affecting versions up to 1.3.13. The vulnerability stems from improper control over the filename parameter used in PHP include or require statements, which allows an attacker to manipulate the input and cause the application to include unintended files from the local filesystem. This can lead to disclosure of sensitive information such as configuration files, source code, or other critical data stored on the server. In some configurations, it may also enable remote code execution if an attacker can upload malicious files or if the server is misconfigured. The vulnerability is due to insufficient input validation or sanitization of user-controlled parameters that influence file inclusion. Although no known public exploits exist at this time, the flaw is classified as a serious security risk because it can be exploited without authentication and does not require user interaction. The affected product, Good Homes, is a popular WordPress theme used for real estate websites, which means many organizations relying on this theme could be vulnerable. The lack of an official patch or mitigation guidance increases the urgency for administrators to implement temporary controls. The vulnerability was published on March 25, 2026, with no CVSS score assigned yet. The issue was reserved in early January 2026 and is tracked by Patchstack. Given the nature of LFI vulnerabilities, attackers can leverage this flaw to escalate privileges, move laterally within the network, or exfiltrate sensitive data, posing a significant risk to confidentiality and integrity of affected systems.

The impact of CVE-2026-22494 on organizations worldwide can be substantial. Successful exploitation can lead to unauthorized disclosure of sensitive files such as configuration files containing database credentials, private keys, or other critical information. This can facilitate further attacks including privilege escalation, remote code execution, or persistent backdoors. For organizations running websites with the Good Homes theme, this vulnerability undermines the confidentiality and integrity of their web infrastructure. It can also damage reputation and trust if customer data is exposed. Since the vulnerability does not require authentication or user interaction, attackers can automate exploitation attempts, increasing the risk of widespread compromise. Additionally, real estate websites often handle personal and financial information, making them attractive targets for cybercriminals. The absence of patches or mitigations at the time of disclosure means organizations must act quickly to reduce exposure. Overall, the vulnerability poses a high risk to availability if attackers leverage it to disrupt services or deploy ransomware. The scope includes any publicly accessible WordPress site using the affected theme versions, which can be globally distributed.

To mitigate CVE-2026-22494, organizations should immediately audit their WordPress installations to identify if the Good Homes theme version 1.3.13 or earlier is in use. If so, they should consider temporarily disabling the theme or restricting access to the affected site until a patch is available. Administrators should implement strict input validation and sanitization on any parameters that influence file inclusion, ideally by whitelisting allowed filenames or paths. Employing a Web Application Firewall (WAF) with rules to detect and block suspicious file inclusion attempts can provide an additional layer of defense. Server-side, disabling PHP functions such as include(), require(), or setting open_basedir restrictions can limit the directories accessible for inclusion. Monitoring web server logs for anomalous requests targeting file inclusion parameters is critical for early detection. Organizations should subscribe to vendor advisories and Patchstack updates to apply official patches promptly once released. Additionally, conducting regular security assessments and penetration tests can help identify similar vulnerabilities proactively. Backup critical data and ensure recovery plans are in place in case of compromise.
