CVE-2026-26890 identifies a SQL Injection vulnerability in Sourcecodester Pharmacy Point of Sale System version 1.0, located in the /pharmacy/manage_product.php script. SQL Injection (CWE-89) occurs when user-supplied input is improperly sanitized before being included in SQL queries, allowing attackers to manipulate the database query structure. In this case, the vulnerability requires an attacker to have high-level privileges (PR:H) and does not require user interaction (UI:N). The attack vector is network-based (AV:N), meaning the attacker can exploit it remotely if they have the necessary credentials. The CVSS v3.1 base score is 2.7, reflecting a low severity primarily due to the requirement for high privileges and limited confidentiality impact. The vulnerability could allow an attacker to extract some sensitive information from the database but does not affect data integrity or system availability. No patches or known exploits are currently available, indicating that the vulnerability is newly disclosed and not yet weaponized in the wild. The lack of affected version details suggests the vulnerability applies to the initial release or all versions up to the disclosure date. Given the nature of the software—a pharmacy POS system—compromise could expose sensitive product or inventory data, which may have regulatory and operational implications.

The primary impact of CVE-2026-26890 is limited unauthorized disclosure of data due to SQL Injection, potentially exposing sensitive pharmacy product information. Since the vulnerability requires high privileges, the risk of external attackers exploiting it without credentials is low. However, if an insider or compromised account with elevated access exploits this flaw, it could lead to unauthorized data access. The vulnerability does not affect data integrity or availability, so it is unlikely to cause data manipulation or service disruption. For organizations handling sensitive health-related data, even limited data leakage can have compliance and reputational consequences. The absence of known exploits reduces immediate risk, but the vulnerability could be targeted in the future once details become widely known. Overall, the impact is low but could be more significant in environments with weak access controls or where the POS system interfaces with broader enterprise systems.

To mitigate CVE-2026-26890, organizations should first implement strict access controls to ensure only trusted users have high-level privileges required to exploit the vulnerability. Input validation and parameterized queries should be enforced in the /pharmacy/manage_product.php code to prevent SQL Injection. Since no official patches are available, code review and manual remediation of the vulnerable script are recommended. Network segmentation can limit exposure of the POS system to untrusted networks. Monitoring and logging database queries and user activities can help detect suspicious behavior indicative of exploitation attempts. Additionally, organizations should prepare to apply patches or updates from the vendor once released. Regular security assessments and penetration testing focusing on SQL Injection vulnerabilities in critical systems like POS software are advised to proactively identify and remediate similar issues.
