CVE-2026-28029 is a high-severity vulnerability affecting the ThemeREX EmojiNation theme, specifically versions from n/a to 1.0.12. This vulnerability allows for PHP Local File Inclusion due to improper control of filename for include/require statements in the PHP program. Exploitation of this vulnerability can potentially lead to unauthorized access and manipulation of server-side files.
The CVSS score for this vulnerability is 8.1, categorizing it as high severity. The high score indicates a significant risk to organizations utilizing this theme, as it enables attackers to leverage this weakness for malicious purposes.
Given the potential impacts of this vulnerability, organizations should prioritize patching immediately to prevent unauthorized access and ensure the integrity of their systems.
Currently, this vulnerability is marked as deferred, which indicates that it may not yet have a formal patch or resolution available. Organizations using the affected versions should remain vigilant and monitor for any updates from the vendor.
Vulnerability Details
The vulnerability arises from improper control of filenames in PHP include/require statements. This allows attackers to perform Local File Inclusion (LFI) attacks, enabling unauthorized access to sensitive files on the server.
The affected product is the ThemeREX EmojiNation theme, with the vulnerability affecting all versions up to and including 1.0.12. The issue was published on March 5, 2026, and is classified under CWE-98.
Technical Analysis
The root cause of this vulnerability is the lack of sufficient validation of user-supplied input for include/require statements in PHP. Attackers can exploit this flaw to include arbitrary files, which may lead to remote code execution or data theft.
The attack vector for this vulnerability is network-based, meaning that an attacker does not require physical access to the server. The complexity of the attack is rated as high, requiring a good understanding of the application structure and its configurations.
No privileges are required, and user interaction is not necessary, allowing attackers to exploit this vulnerability without any direct engagement with the target system.
The potential impacts include high confidentiality, integrity, and availability risks, as attackers may gain access to sensitive data, modify files, or disrupt services.
Risk & Impact Analysis
Organizations using the affected versions of ThemeREX EmojiNation are at a significant risk due to the potential for Local File Inclusion attacks. The blast radius of this vulnerability is substantial, as it could lead to full compromise of the application's integrity and confidentiality.
Given the high CVSS score of 8.1 and the deferred status of the vulnerability, organizations should address this issue in their priority patch cycle. The lack of a known exploit currently decreases immediate threat levels, but organizations should remain vigilant.
