CVE-2026-28022: High Vulnerability in ThemeREX Foodie

CVE-2026-28022 is classified as a high-severity vulnerability, stemming from improper control of the filename for include/require statements in the PHP program associated with ThemeREX Foodie. This vulnerability allows PHP Local File Inclusion, exposing the application to severe risks. The CVSS score for this vulnerability is 8.1, indicating a high level of threat that organizations must address promptly.

Risk to organizations includes unauthorized access to sensitive files, which could lead to data breaches and exploitation of the server. Given that this vulnerability exists in versions of the Foodie theme up to and including 1.14, organizations utilizing this theme should take it seriously and implement necessary patches. The urgency for defenders is high, as the attack vector is through the network with high impact on confidentiality, integrity, and availability.

Despite the high potential for exploitation, there are currently no known public exploits or proof-of-concept (PoC) code linked to this vulnerability. However, this should not lead to complacency; organizations must prioritize remediation efforts to safeguard their systems.

Organizations should prioritize patching immediately, as this vulnerability poses significant risks if left unaddressed. Implementing security measures and updating to the latest version of the Foodie theme will help mitigate the potential for exploitation.

Vulnerability Details

The vulnerability in question is characterized as an 'Improper Control of Filename for Include/Require Statement in PHP Program', specifically identified as a 'PHP Remote File Inclusion' vulnerability. This issue affects the ThemeREX Foodie version 1.14 and earlier, which could allow attackers to include arbitrary files, leading to local file inclusion vulnerabilities.

The CVSS score of 8.1 indicates a high severity, with a vector string of 'CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H'. This reflects a network attack vector, high attack complexity, and no privileges or user interaction required to exploit the vulnerability. The impacts on confidentiality, integrity, and availability are rated as high.

The CWE classification for this vulnerability is CWE-98, which pertains to 'Improper Control of Filename for Include/Require Statement in PHP Program'.

Technical Analysis

The root cause of this vulnerability lies in the improper validation of user input for file inclusion, allowing attackers to manipulate the file path and potentially gain access to sensitive files on the server. The attack vector is primarily network-based, requiring no user interaction or privileges to exploit. The complexity of the attack is considered high, as it relies on the correct construction of file paths and the server's configuration.

The impacts of this vulnerability are significant. Attackers may leverage this exploit to access confidential data, compromise the integrity of the server, and disrupt availability by including malicious files. Organizations must ensure that they implement necessary security measures to prevent such vulnerabilities from being exploited.

Risk & Impact Analysis

The potential impact of CVE-2026-28022 on organizations is considerable. If exploited, attackers could gain unauthorized access to sensitive information, leading to data breaches and significant financial loss. The vulnerability's ability to allow local file inclusion means that the blast radius is substantial, affecting not just the application but potentially other systems and data integrated with it.

Given the high CVSS score of 8.1 and the current lack of known exploits, organizations should still act with a sense of urgency. Although there is no active exploitation reported, the potential for future attacks remains a concern, and organizations should prioritize remediation efforts during their patch cycle.

The overall risk assessment indicates a high need for immediate attention to this vulnerability. Organizations must ensure they stay updated on the latest patches and conduct regular security assessments to identify and mitigate risks effectively.

Exploitation Status

Affected Versions

The affected versions of the ThemeREX Foodie include all versions from n/a through 1.14. Organizations using this theme should verify their versions and apply patches where necessary.

Mitigation & Remediation

To mitigate the risks associated with CVE-2026-28022, organizations should update the ThemeREX Foodie to the latest version, ensuring that all security patches are applied. In cases where immediate updates are not possible, further security measures should be implemented, such as restricting file inclusion and auditing the web server’s configuration.

Additionally, organizations can benefit from engaging in penetration testing to identify potential weaknesses in their applications and infrastructure.

Detection Guidance

Organizations should monitor logs for unusual file access patterns, particularly those associated with the include or require statements in PHP. Behavioral anomalies, such as unexpected file inclusion errors or unauthorized file access attempts, should be investigated promptly.

Network signatures may also be established to detect any attempts at exploiting this vulnerability, especially when combined with application layer monitoring to capture potential exploitation attempts.

AppSecure Threat Intelligence Insight

The long-term significance of CVE-2026-28022 underscores the importance of rigorous file handling practices in PHP applications. This vulnerability reflects a broader trend of misconfiguration leading to severe security risks. Security teams should take this as a lesson to reinforce their secure coding practices and ensure that all file inclusions are properly validated.

Monitoring for similar vulnerabilities is critical, as attackers continuously seek ways to exploit weaknesses in web applications. Engaging in a comprehensive penetration testing methodology can help organizations identify and address such vulnerabilities proactively.

Furthermore, organizations should invest in training and awareness programs to ensure developers understand the implications of file inclusion vulnerabilities, fostering a culture of security from the ground up.
