CVE-2026-25027 is a vulnerability identified in the ThemeMove Unicamp WordPress theme, specifically involving improper control over the filename parameter used in PHP include or require statements. This vulnerability allows for Local File Inclusion (LFI), where an attacker can manipulate the input to include arbitrary files from the server's filesystem. The affected versions are up to and including 2.7.1, with no versions beyond that confirmed safe. LFI vulnerabilities can lead to information disclosure by reading sensitive files such as configuration files, password files, or application source code. In some cases, if combined with other vulnerabilities or misconfigurations, it can lead to remote code execution. The vulnerability arises because the theme does not properly validate or sanitize the input controlling the include/require filename, allowing attackers to traverse directories or specify unintended files. No CVSS score has been assigned yet, and no public exploits or patches are currently known. The vulnerability was published in early 2026, and the vendor or community has not yet released a fix. This vulnerability is particularly dangerous in web environments where the theme is actively used, as it can be exploited remotely without authentication or user interaction, depending on the site setup. Attackers could leverage this to compromise the confidentiality and integrity of the affected web server and potentially pivot to further internal network attacks.

For European organizations, the impact of CVE-2026-25027 can be significant, especially for those relying on WordPress sites using the ThemeMove Unicamp theme. Successful exploitation can lead to unauthorized disclosure of sensitive data such as credentials, internal configuration files, or customer information, undermining confidentiality. Integrity may be compromised if attackers manage to execute arbitrary code or modify files, potentially defacing websites or implanting malware. Availability impact is generally lower but could occur if attackers disrupt web services or cause server crashes. Organizations in sectors like finance, healthcare, government, and e-commerce are particularly at risk due to the sensitivity of their data and regulatory requirements such as GDPR. The lack of a patch and known exploits means organizations must proactively assess and mitigate risk. The vulnerability could also be leveraged as a foothold for further attacks within corporate networks, increasing overall risk exposure.

1. Immediate code audit of the ThemeMove Unicamp theme to identify and restrict all include/require statements to safe, fixed paths or whitelist allowed files. 2. Implement strict input validation and sanitization to prevent directory traversal or arbitrary file inclusion. 3. If possible, upgrade to a version of the theme that addresses this vulnerability once released. 4. Employ Web Application Firewalls (WAFs) with rules to detect and block suspicious requests attempting file inclusion attacks. 5. Monitor web server logs for unusual access patterns or attempts to include unexpected files. 6. Restrict file permissions on the web server to limit access to sensitive files that could be included. 7. Consider isolating the web server environment to minimize impact if exploited. 8. Educate developers and administrators about secure coding practices to prevent similar vulnerabilities. 9. Regularly back up website data and configurations to enable quick recovery if compromised. 10. Engage with the theme vendor or community for updates and patches.
