CVE-2026-25379 is a vulnerability classified as Improper Control of Filename for Include/Require Statement in PHP programs, specifically affecting the StreamVid product developed by jwsthemes. This vulnerability allows Remote File Inclusion (RFI) or Local File Inclusion (LFI), where an attacker can manipulate the filename parameter used in PHP include or require statements to load arbitrary files. The affected versions include all releases prior to 6.8.6. The root cause is insufficient validation or sanitization of user-supplied input that determines which files are included during runtime. By exploiting this flaw, an attacker can cause the web application to execute malicious PHP code hosted on a remote server or access sensitive local files, potentially leading to full server compromise. Although no exploits have been reported in the wild yet, the vulnerability is publicly disclosed and thus poses a risk. The lack of a CVSS score indicates that the vulnerability is newly published and awaiting further analysis. The vulnerability impacts the confidentiality, integrity, and availability of affected systems, as attackers can execute arbitrary code, steal data, or disrupt services. StreamVid is a PHP-based video streaming platform, commonly deployed on web servers, making it a target for attackers seeking to exploit web application vulnerabilities. The vulnerability is particularly dangerous because it does not require authentication or user interaction, making automated exploitation feasible. The absence of official patches at the time of disclosure means organizations must apply immediate mitigations to reduce risk.

The impact of CVE-2026-25379 is significant for organizations using StreamVid versions prior to 6.8.6. Successful exploitation can lead to remote code execution, allowing attackers to execute arbitrary commands on the affected server. This can result in full system compromise, data theft, defacement, or use of the server as a pivot point for further attacks within the network. Confidentiality is at risk due to potential unauthorized access to sensitive files. Integrity can be compromised by injecting malicious code or altering application behavior. Availability may be affected if attackers disrupt service or deploy ransomware. Since StreamVid is used for video streaming, service disruption can impact business continuity and user experience. The vulnerability's ease of exploitation without authentication increases the threat level, especially for publicly accessible web servers. Organizations with inadequate input validation, weak web server configurations, or lacking network segmentation are at higher risk. The absence of known exploits in the wild currently limits immediate widespread damage but does not reduce the urgency for mitigation. Attackers may develop exploits rapidly following public disclosure, increasing the threat landscape.

To mitigate CVE-2026-25379, organizations should prioritize upgrading StreamVid to version 6.8.6 or later once available. In the absence of an official patch, immediate steps include implementing strict input validation and sanitization on all parameters used in include or require statements to ensure only authorized files can be loaded. Employ whitelisting of allowable file paths and names rather than blacklisting. Disable remote file inclusion in PHP by setting 'allow_url_include' to 'Off' in the php.ini configuration. Restrict 'allow_url_fopen' to 'Off' if remote file access is not required. Use web application firewalls (WAFs) to detect and block suspicious requests attempting file inclusion attacks. Conduct thorough code reviews to identify and refactor vulnerable include/require statements. Limit web server permissions to prevent execution of unauthorized files and isolate web applications using containerization or sandboxing. Monitor logs for unusual file inclusion attempts and anomalous behavior. Regularly back up critical data and maintain incident response plans to quickly address potential compromises. Educate developers on secure coding practices to prevent similar vulnerabilities in the future.
