CVE-2026-26705 identifies a SQL Injection vulnerability in the Pharmacy Point of Sale System version 1.0, specifically within the /pharmacy/view_product.php endpoint. SQL Injection occurs when untrusted input is improperly sanitized and directly incorporated into SQL queries, allowing attackers to alter the intended query logic. In this case, the vulnerable script likely accepts user-supplied parameters to view product details but fails to properly validate or parameterize these inputs. An attacker could exploit this by injecting crafted SQL code to retrieve, modify, or delete sensitive data stored in the backend database. This could include patient information, transaction records, or inventory data. The vulnerability does not require authentication, meaning any remote attacker with network access to the application could attempt exploitation. No CVSS score has been assigned yet, and no patches or known exploits are currently documented. However, given the critical role of pharmacy POS systems in healthcare and retail, the risk is substantial. The lack of authentication and the direct impact on data confidentiality and integrity elevate the threat level. The vulnerability highlights the importance of secure coding practices such as prepared statements and rigorous input validation in web applications handling sensitive data.

If exploited, this SQL Injection vulnerability could lead to unauthorized disclosure of sensitive pharmacy and customer data, including personal health information and payment details. Attackers might also manipulate or delete critical data, disrupting pharmacy operations and potentially causing financial losses or regulatory compliance violations. The integrity of transaction records could be compromised, affecting billing and inventory management. Additionally, attackers could escalate their access within the network if database credentials or other sensitive information are exposed. This could lead to broader system compromise. The availability impact is generally lower but could occur if destructive SQL commands are executed. Given the sensitive nature of pharmacy data and the critical role of POS systems in healthcare supply chains, the overall impact on organizations worldwide is significant, especially for those relying on this specific software or similar vulnerable systems.

Organizations should immediately review and update the affected Pharmacy Point of Sale System to a patched version once available. In the absence of an official patch, implement strict input validation and sanitization on all user-supplied data, especially parameters passed to /pharmacy/view_product.php. Employ parameterized queries or prepared statements to prevent direct injection of SQL code. Conduct thorough code audits to identify and remediate similar vulnerabilities in other parts of the application. Restrict network access to the POS system to trusted users and internal networks only, using firewalls and VPNs. Monitor database logs for unusual query patterns that may indicate attempted exploitation. Regularly back up critical data and test restoration procedures to mitigate potential data loss. Educate developers on secure coding practices and the risks of SQL Injection. Finally, consider deploying Web Application Firewalls (WAFs) with SQL Injection detection rules as an additional protective layer.
