CVE-2026-0546 identifies a SQL injection vulnerability in the code-projects Content Management System version 1.0, specifically within an unspecified function in the search.php file. The vulnerability arises from improper sanitization of the 'Value' argument, which an attacker can manipulate to inject malicious SQL code. This flaw allows remote attackers to execute arbitrary SQL commands on the backend database without any authentication or user interaction, due to the vulnerability's remote network attack vector and low attack complexity. The impact includes potential unauthorized data disclosure, modification, or deletion, which compromises confidentiality, integrity, and availability. The vulnerability has a CVSS 4.0 base score of 6.9, reflecting medium severity with partial impact on confidentiality, integrity, and availability. Although no public exploits are currently documented in the wild, the public disclosure increases the likelihood of exploitation attempts. The vulnerability affects only version 1.0 of the CMS, which may limit exposure depending on the adoption rate of this version. The lack of patches at the time of reporting necessitates immediate mitigation through secure coding practices and monitoring. The vulnerability does not require privileges or user interaction, increasing its risk profile for internet-facing deployments. Organizations using this CMS should conduct thorough code reviews and implement parameterized queries or prepared statements to prevent SQL injection. Additionally, web application firewalls (WAFs) can provide temporary protection by filtering malicious input targeting the vulnerable parameter.

The SQL injection vulnerability in code-projects CMS 1.0 can have significant impacts on organizations worldwide. Exploitation can lead to unauthorized access to sensitive data stored in backend databases, including user credentials, personal information, or proprietary business data. Attackers could modify or delete data, disrupting business operations and damaging data integrity. The vulnerability's remote exploitability without authentication increases the attack surface, especially for internet-facing CMS deployments. This can result in data breaches, loss of customer trust, regulatory penalties, and potential financial losses. Additionally, attackers might leverage the vulnerability to escalate privileges or pivot within the network, leading to broader compromise. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate it, as public disclosure often precedes active exploitation. Organizations relying on this CMS version for critical web services are particularly vulnerable, and the impact is exacerbated if the CMS hosts sensitive or regulated data. The medium severity rating suggests moderate but meaningful risk, necessitating prompt mitigation to prevent exploitation and protect organizational assets.

To mitigate CVE-2026-0546, organizations should: 1) Immediately assess their environment to identify any deployments of code-projects CMS version 1.0. 2) Apply vendor-provided patches or updates as soon as they become available; if no patch exists, consider upgrading to a newer, secure version of the CMS. 3) Implement input validation and sanitization for all user-supplied data, especially the 'Value' parameter in search.php, to prevent injection of malicious SQL code. 4) Refactor the vulnerable code to use parameterized queries or prepared statements, which effectively neutralize SQL injection attempts. 5) Deploy a web application firewall (WAF) with rules designed to detect and block SQL injection patterns targeting the CMS. 6) Conduct regular security audits and penetration testing focused on injection vulnerabilities. 7) Monitor logs and network traffic for unusual database queries or error messages indicative of attempted exploitation. 8) Restrict database user privileges to the minimum necessary to limit the impact of any successful injection. 9) Educate developers and administrators about secure coding practices and the risks of SQL injection. 10) Consider isolating or segmenting the CMS environment to reduce potential lateral movement in case of compromise.
