CVE-2026-5553 describes a SQL Injection vulnerability discovered in itsourcecode Online Cellphone System, specifically within the parameter handling functionality of the /cp/available.php file. Successful exploitation could allow an attacker to manipulate the database, potentially leading to unauthorized data access or modification. This vulnerability affects versions 1.0.0 through 1.0, and a fix is expected from the vendor.
The SQL Injection vulnerability in itsourcecode Online Cellphone System allows attackers to inject arbitrary SQL code into database queries. This can lead to a wide range of malicious activities, including unauthorized access to sensitive data such as user credentials, financial information, and personal details. An attacker could also modify or delete data, potentially disrupting the system's functionality or causing data loss. Given the publicly available exploit, the risk of exploitation is significant, particularly for systems with weak input validation or inadequate security configurations. The potential blast radius extends to all data stored within the database, making this a critical security concern.
CVE-2026-5553 is publicly known and has a publicly available exploit, increasing the likelihood of exploitation. The vulnerability has been added to the NVD database on 2026-04-05. The EPSS score is likely to be medium due to the availability of a public exploit and the potential for significant impact. There are no confirmed reports of active exploitation campaigns at this time, but the ease of exploitation warrants immediate attention.

The primary mitigation for CVE-2026-5553 is to upgrade to a patched version of itsourcecode Online Cellphone System as soon as it becomes available. Until a patch is released, consider implementing temporary workarounds such as input validation and parameterized queries to sanitize user-supplied data before it is used in SQL statements. Web application firewalls (WAFs) configured to detect and block SQL Injection attempts can also provide an additional layer of protection. Monitor application logs for suspicious SQL queries or error messages that might indicate an attempted exploit.
Update the system to a corrected version that resolves the SQL injection vulnerability in the /cp/available.php file. Review and sanitize the 'Name' input to prevent the execution of malicious SQL code. Implement data validation and escaping on all user inputs.
