CVE-2025-68987 is a critical vulnerability classified as a Remote File Inclusion (RFI) flaw in the Edge-Themes Cinerama WordPress theme, which is tailored for movie studios and filmmakers. The vulnerability arises from improper control over the filename parameter used in PHP's include or require statements, allowing an attacker to specify arbitrary files to be included and executed by the server. This flaw affects all versions of the Cinerama theme up to and including version 2.4. Because PHP include/require statements execute code from the specified files, an attacker can remotely include malicious PHP scripts hosted on external servers, leading to remote code execution (RCE). The vulnerability requires no authentication and no user interaction, making it trivially exploitable over the network. The CVSS 3.1 base score of 9.8 reflects the critical nature of this vulnerability, with attack vector being network-based, low attack complexity, no privileges required, no user interaction, and high impact on confidentiality, integrity, and availability. The vulnerability can lead to full system compromise, data exfiltration, defacement, or pivoting within the victim's network. Although no known exploits have been reported in the wild yet, the widespread use of WordPress and the popularity of the Cinerama theme in the media sector make this a high-risk issue. The lack of official patches or updates at the time of disclosure increases the urgency for mitigation.

For European organizations, especially those in the media, entertainment, and creative industries that rely on WordPress and specifically the Cinerama theme, this vulnerability poses a severe risk. Successful exploitation can lead to complete compromise of web servers, exposing sensitive intellectual property, client data, and internal communications. The integrity of websites can be undermined, leading to reputational damage and loss of customer trust. Availability may also be impacted if attackers deploy ransomware or defacement attacks. Given the criticality and ease of exploitation, attackers could leverage this vulnerability to establish persistent footholds, move laterally within networks, or launch further attacks against European infrastructure. Regulatory implications under GDPR may also arise due to potential data breaches. The threat is particularly acute for organizations that have not implemented timely patching or lack robust web application security controls.

Immediate mitigation steps include: 1) Updating the Cinerama theme to a patched version once available from Edge-Themes. If no patch exists yet, consider temporarily disabling or removing the theme to prevent exploitation. 2) Implement strict input validation and sanitization on all parameters that control file inclusion to prevent injection of arbitrary file paths or URLs. 3) Deploy a Web Application Firewall (WAF) with rules to detect and block suspicious include/require parameter usage and known attack patterns related to RFI. 4) Restrict PHP configuration settings such as disabling allow_url_include and enabling open_basedir restrictions to limit file inclusion to trusted directories. 5) Conduct thorough security audits and monitoring of web server logs for unusual requests or file access patterns. 6) Educate site administrators on the risks and ensure timely application of security updates. 7) Employ network segmentation to limit the impact of a compromised web server on internal systems. These measures, combined, reduce the attack surface and improve detection and response capabilities.
