CVE-2026-5955 Overview
CVE-2026-5955 is a SQL injection vulnerability affecting Inrove Software and Internet Services BiEticaret e-commerce platform. The flaw stems from improper neutralization of special elements used in SQL commands [CWE-89]. All versions of BiEticaret prior to v3.3.57 are affected. Remote attackers can exploit this issue over the network without authentication or user interaction. Successful exploitation compromises the confidentiality, integrity, and availability of the backing database.
Critical Impact
Unauthenticated remote attackers can execute arbitrary SQL statements against the BiEticaret database, enabling data theft, data modification, and full database compromise.

Technical Details for CVE-2026-5955
Vulnerability Analysis
CVE-2026-5955 is classified as an SQL injection weakness [CWE-89] in the BiEticaret e-commerce application. The application fails to properly sanitize or parameterize user-controlled input before incorporating it into SQL queries. Attackers can inject crafted SQL syntax into request parameters processed by vulnerable endpoints. The injected payload alters query semantics and causes the database engine to execute attacker-controlled logic.
Because the attack vector is network-based and requires no privileges or user interaction, exploitation can be automated at scale. An attacker can enumerate database schemas, extract customer records, read stored credentials, and modify or delete data. In many SQL injection scenarios, chained techniques allow file read, file write, or command execution on the database server depending on database privileges.
The EPSS probability is 0.436% (percentile 35.141) as of 2026-07-09. No public proof-of-concept exploit has been recorded at publication time, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Root Cause
The root cause is the concatenation of untrusted input into SQL statements without the use of parameterized queries or prepared statements. Input validation and output encoding routines fail to neutralize characters such as single quotes, comment sequences, and statement terminators. See the Siber Güvenlik Notification TR-26-0519 for advisory details.
Attack Vector
An unauthenticated remote attacker sends crafted HTTP requests to a vulnerable BiEticaret endpoint. The request contains SQL metacharacters injected into a parameter that flows into a database query. The database executes the modified query and returns data or performs actions selected by the attacker. No verified public exploit code is available; refer to the vendor advisory for technical specifics.
Detection Methods for CVE-2026-5955
Indicators of Compromise
- Web server access logs containing SQL metacharacters such as ', --, UNION SELECT, SLEEP(, or INFORMATION_SCHEMA in query strings or POST bodies targeting BiEticaret endpoints.
- Database error messages returned in HTTP responses referencing syntax errors or malformed queries.
- Unusual outbound traffic from the database host following anomalous query patterns.
Detection Strategies
- Deploy web application firewall (WAF) rules that detect SQL injection signatures on requests to BiEticaret application paths.
- Enable database query auditing to log queries that reference sensitive tables or use stacked statements.
- Correlate spikes in HTTP 500 responses with request parameters containing SQL syntax to identify probing attempts.
Monitoring Recommendations
- Monitor for repeated failed queries, long-running queries, and boolean-based timing patterns indicative of blind SQL injection.
- Alert on any read access to authentication tables or bulk SELECT operations against customer records.
- Track application-layer error rates and correlate with source IP reputation to surface automated exploitation attempts.
How to Mitigate CVE-2026-5955
Immediate Actions Required
- Upgrade BiEticaret to version v3.3.57 or later without delay.
- Restrict network exposure of the BiEticaret application to trusted sources until the patch is applied.
- Review web server and database logs for indicators of prior exploitation attempts.
- Rotate database credentials and any secrets that may have been accessible through the application.
Patch Information
Inrove Software and Internet Services has addressed the issue in BiEticaret v3.3.57. Administrators should follow vendor upgrade procedures and verify the running version after deployment. Refer to the Siber Güvenlik Notification TR-26-0519 for advisory details.
Workarounds
- Place a WAF in front of BiEticaret with SQL injection rulesets enabled in blocking mode.
- Enforce least-privilege database accounts so the application user cannot read sensitive tables or execute administrative commands.
- Disable verbose database error messages in production to reduce information leakage useful to attackers.
