CVE-2026-3046 identifies a SQL injection vulnerability in the itsourcecode E-Logbook with Health Monitoring System for COVID-19 version 1.0. The flaw exists in the /check_profile_old.php script, where the profile_id parameter is improperly sanitized, allowing attackers to inject malicious SQL code. This injection can lead to unauthorized access, modification, or deletion of database records. The vulnerability is remotely exploitable without requiring authentication or user interaction, increasing its risk profile. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P) indicates network attack vector, low attack complexity, no privileges or user interaction needed, and partial impacts on confidentiality, integrity, and availability. Although no confirmed exploits in the wild have been reported, public disclosure of exploit code raises the likelihood of future attacks. The affected product is used for COVID-19 health monitoring, which typically involves sensitive personal and health data, making the impact potentially severe. The vulnerability could allow attackers to extract sensitive health information, alter records, or disrupt system availability, undermining trust and compliance with health data regulations. The lack of available patches necessitates immediate mitigation through secure coding practices and access controls.

The impact of CVE-2026-3046 is significant for organizations using the itsourcecode E-Logbook with Health Monitoring System for COVID-19, as it enables remote attackers to perform SQL injection attacks without authentication. This can lead to unauthorized disclosure of sensitive health data, modification or deletion of critical records, and potential disruption of health monitoring services. Such breaches could violate privacy regulations (e.g., HIPAA, GDPR), damage organizational reputation, and impair public health response efforts. The partial impact on confidentiality, integrity, and availability means attackers could both steal and manipulate data or cause denial of service. Given the system’s role in COVID-19 health monitoring, exploitation could have direct consequences on patient care and epidemiological tracking. The public availability of exploit code increases the risk of widespread attacks, especially targeting healthcare providers and government agencies relying on this software. Organizations worldwide that have deployed this system or similar vulnerable versions face elevated risks of data breaches and operational disruptions.

To mitigate CVE-2026-3046, organizations should immediately implement input validation and sanitization on the profile_id parameter to prevent SQL injection. Employing parameterized queries or prepared statements is critical to ensure that user inputs are not executed as SQL commands. Restrict access to the /check_profile_old.php endpoint through network segmentation, firewalls, or web application firewalls (WAF) with SQL injection detection rules. Monitor logs for suspicious database queries or unusual access patterns indicative of exploitation attempts. If possible, upgrade or patch the software once a vendor fix becomes available. Conduct a thorough security review of all input handling in the application to identify and remediate similar vulnerabilities. Additionally, enforce strict access controls and authentication mechanisms around sensitive health data systems. Regularly back up databases and implement incident response plans to quickly recover from potential data integrity or availability compromises. Educate development teams on secure coding practices to prevent future injection flaws.
