CVE-2026-30463 identifies a SQL injection vulnerability in Daylight Studio FuelCMS version 1.5.2, located in the /controllers/Login.php file. SQL injection occurs when untrusted input is improperly sanitized and directly included in SQL queries, allowing attackers to manipulate database commands. In this case, the login controller fails to adequately sanitize user-supplied input, enabling an attacker to inject arbitrary SQL code. This can lead to unauthorized retrieval or modification of sensitive data stored in the backend database, such as user credentials, personal information, or configuration data. The vulnerability resides in a critical authentication component, increasing the potential impact. Although no exploits have been observed in the wild yet, the flaw is publicly disclosed and could be targeted by attackers once exploit code becomes available. No CVSS score has been assigned, and no official patches or mitigation advisories are currently published. The absence of authentication requirements and the ease of triggering the vulnerability through login requests make it a significant threat. FuelCMS is a content management system used by various organizations for web application development, and version 1.5.2 is specifically affected. The vulnerability underscores the importance of secure coding practices such as input validation and use of parameterized queries to prevent injection attacks.

The SQL injection vulnerability in FuelCMS 1.5.2 can have severe consequences for affected organizations. Attackers exploiting this flaw could gain unauthorized access to sensitive data, including user credentials and personal information, leading to data breaches and privacy violations. They may also alter or delete data, compromising data integrity and potentially disrupting business operations. In some cases, attackers could escalate privileges or execute administrative commands on the database server, resulting in full system compromise. The vulnerability affects the login component, a critical entry point, increasing the risk of widespread exploitation. Organizations relying on FuelCMS for public-facing websites or internal applications are at risk of reputational damage, regulatory penalties, and financial losses if exploited. The lack of known exploits currently provides a window for proactive mitigation, but the public disclosure increases the likelihood of future attacks. The impact extends to availability if attackers perform destructive actions or cause denial of service through database manipulation.

To mitigate CVE-2026-30463, organizations should first identify all instances running FuelCMS version 1.5.2. Until an official patch is released, immediate steps include implementing strict input validation and sanitization on all user inputs, especially those processed by the /controllers/Login.php component. Employ parameterized queries or prepared statements to prevent SQL injection. Review and harden database user permissions to limit the potential damage from exploitation. Enable detailed logging and monitoring of login attempts to detect suspicious activities indicative of exploitation attempts. Consider deploying web application firewalls (WAFs) with rules designed to detect and block SQL injection payloads targeting FuelCMS. Educate development teams on secure coding practices to prevent similar vulnerabilities in the future. Once an official patch or update is available from FuelCMS, apply it promptly. Additionally, conduct regular security assessments and penetration testing to identify and remediate injection flaws proactively.
