CVE-2025-26889 is a Local File Inclusion (LFI) vulnerability affecting hockeydata LOS versions up to and including 1.2.4. The root cause is improper control of filenames used in PHP include or require statements, which allows an attacker to manipulate the file path parameter to include arbitrary local files on the server. This can lead to sensitive information disclosure, such as configuration files, source code, or credentials, and may facilitate further attacks like remote code execution if combined with other vulnerabilities or misconfigurations. The vulnerability arises because the application does not properly validate or sanitize user-supplied input that determines the file to be included. Although the vulnerability is classified as a Local File Inclusion rather than Remote File Inclusion, it still poses significant risk as attackers can read critical files or escalate privileges. No public exploits are currently known, and no official patches have been linked yet. The vulnerability was reserved in February 2025 and published in April 2025, indicating recent discovery. The absence of a CVSS score requires an independent severity assessment based on the impact and exploitability characteristics. This vulnerability affects the hockeydata LOS product, which is a PHP-based system used in specific domains, likely related to sports data or management. Organizations using affected versions should consider this vulnerability critical to address promptly.

The impact of CVE-2025-26889 can be severe for organizations using hockeydata LOS. Successful exploitation allows attackers to read arbitrary files on the server, potentially exposing sensitive data such as database credentials, configuration files, or user information. This can lead to further compromise of the system, including privilege escalation or remote code execution if attackers can leverage other vulnerabilities or upload malicious files. The confidentiality and integrity of the affected systems are at risk, and availability could be indirectly impacted if attackers disrupt services or cause system instability. Organizations handling sensitive or regulated data may face compliance violations and reputational damage. Since hockeydata LOS is a specialized product, the scope of affected systems may be limited, but any deployment in critical infrastructure or business operations could have significant consequences. The lack of known exploits in the wild reduces immediate risk but does not diminish the urgency of mitigation, as attackers often develop exploits rapidly after public disclosure.

To mitigate CVE-2025-26889, organizations should take the following specific actions: 1) Immediately upgrade hockeydata LOS to a version that patches this vulnerability once available. 2) In the absence of a patch, apply input validation and sanitization on all parameters controlling file inclusion to restrict input to a whitelist of allowed filenames or directories. 3) Implement PHP configuration hardening, such as disabling allow_url_include and restricting open_basedir to limit accessible filesystem paths. 4) Employ Web Application Firewalls (WAFs) with rules designed to detect and block attempts to exploit file inclusion vulnerabilities. 5) Conduct code reviews and security testing focusing on file inclusion logic to identify and remediate similar issues. 6) Monitor logs for suspicious file access patterns indicative of LFI attempts. 7) Isolate the hockeydata LOS environment with least privilege principles to minimize impact if exploited. 8) Educate developers and administrators about secure coding practices related to file handling in PHP. These measures collectively reduce the risk of exploitation and limit potential damage.
