CVE-2026-26885 identifies an SQL Injection vulnerability in the Sourcecodester Online Men's Salon Management System version 1.0. The vulnerability exists in the delete_service function accessed via the /classes/Master.php endpoint. This flaw arises from insufficient sanitization of user-supplied input parameters, allowing an authenticated user with high privileges to inject arbitrary SQL commands. The vulnerability is categorized under CWE-89, which pertains to improper neutralization of special elements used in SQL commands. The CVSS 3.1 base score is 2.7, reflecting a low severity primarily because exploitation requires network access, low attack complexity, and high privileges, with no user interaction needed. The impact is limited to confidentiality, with no direct effect on integrity or availability. No patches or fixes have been released yet, and there are no known active exploits in the wild. The vulnerability could potentially allow attackers to retrieve sensitive data from the backend database but not modify or delete data or disrupt service. The lack of a specified affected version beyond v1.0 suggests this issue may be confined to that release. The vulnerability highlights the need for secure coding practices, particularly input validation and parameterized queries, to prevent SQL Injection attacks.

The primary impact of this vulnerability is limited unauthorized disclosure of data due to SQL Injection. Since the vulnerability requires high privileges and authenticated access, the risk of external attackers exploiting it remotely without credentials is low. However, insider threats or compromised accounts with elevated privileges could leverage this flaw to extract sensitive information from the database. The absence of integrity or availability impact means attackers cannot alter or delete data or cause denial of service through this vulnerability. Organizations using this system may face data confidentiality risks, especially if sensitive customer or business data is stored in the affected database. While no known exploits exist currently, the vulnerability could be targeted in the future if attackers gain privileged access. The limited scope and low severity reduce the overall threat level but do not eliminate the need for remediation, particularly in environments with sensitive data or regulatory compliance requirements.

To mitigate this vulnerability, organizations should implement strict input validation and sanitization on all user-supplied data, especially parameters passed to SQL queries. Employing parameterized queries or prepared statements will prevent SQL Injection by separating code from data. Restrict access to the delete_service function to only trusted and necessary users with the minimum required privileges. Conduct a thorough code review of the Master.php class and related database interaction code to identify and remediate similar injection flaws. Monitor logs for unusual database query patterns that may indicate attempted exploitation. If possible, isolate the affected system within a segmented network to reduce exposure. Since no official patch is available, consider applying custom fixes or vendor updates once released. Additionally, implement strong authentication and session management controls to prevent unauthorized privilege escalation. Regularly back up data to enable recovery in case of compromise. Finally, educate developers on secure coding practices to prevent recurrence of such vulnerabilities.
