CVE-2026-5955 -- CVSS 9.8 Vulnerability Briefing

CVE-2026-5955 | CVSS 9.8 (Critical) | Exploit: No known exploit

What Is It

CVE-2026-5955 is a critical SQL injection vulnerability in BiEticaret, an e-commerce platform developed by Inrove Software and Internet Services, affecting the application's database query handling layer.

Technical Detail

The vulnerability stems from improper neutralization of user-supplied input before it is incorporated into SQL commands, a classic CWE-89 condition. An unauthenticated or low-privileged attacker can craft malicious input to manipulate backend database queries, potentially enabling unauthorized data extraction, authentication bypass, or full database compromise depending on the database user's privilege level. In worst-case configurations where the application database account has elevated permissions, this could extend to operating system command execution via database-native functions such as xp_cmdshell or similar mechanisms.

Exploitation Status

No known exploit code has been publicly observed or confirmed at this time. The vulnerability is not currently listed in CISA's Known Exploited Vulnerabilities catalog. Despite the absence of confirmed exploitation, the critical CVSS score of 9.8 reflects the low attack complexity and high potential impact, meaning functional exploitation would require minimal attacker skill once a target is identified.

Who Is Targeting This

No specific threat actor attribution at this time. Neither confirmed nor reported threat actor activity has been associated with this CVE as of July 16, 2026.

What To Do

Organizations running BiEticaret should contact Inrove Software and Internet Services immediately to obtain a patched version or vendor guidance, as no specific patch version is confirmed in current public disclosures. As an interim measure, deploy a web application firewall with SQL injection detection rules in front of any BiEticaret instance and restrict direct database access to application service accounts with least-privilege configurations. Audit application logs for anomalous SQL syntax patterns in input fields, particularly those involving quote characters, comment sequences, or UNION-based payloads. If the application is internet-facing and a patch is not immediately available, consider taking it offline or restricting access to trusted IP ranges until remediation is confirmed.
