This vulnerability (CVE-2026-5955) in BiEticaret before version 3.3.57 is due to improper neutralization of special elements used in SQL commands, classified as CWE-89 (SQL Injection). It allows an attacker to inject malicious SQL code, potentially leading to unauthorized data access, modification, or deletion. The CVSS 3.1 base score is 9.8, reflecting network attack vector, low attack complexity, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability. No official fix or patch has been documented in the provided data, and the product is not a cloud service, so remediation depends on vendor patch availability.
