CVE-2026-52470 Overview
CVE-2026-52470 is a SQL injection vulnerability in Crocus version 1.3.44. The flaw resides in the RecordStateMapper.xml file, where user-supplied input is concatenated into SQL statements without proper sanitization. A remote, unauthenticated attacker can exploit this weakness over the network to inject arbitrary SQL queries. Successful exploitation enables privilege escalation and full compromise of the underlying database. The issue is tracked under CWE-89: Improper Neutralization of Special Elements used in an SQL Command.
Critical Impact
Remote attackers can escalate privileges and access, modify, or destroy database contents without authentication or user interaction.

Technical Details for CVE-2026-52470
Vulnerability Analysis
The vulnerability exists in the RecordStateMapper.xml MyBatis mapper file used by Crocus v1.3.44. Mapper files in MyBatis define the SQL statements executed against the backing database. When a mapper concatenates request parameters directly into a statement using ${} substitution rather than the parameterized #{} placeholder, attacker-controlled input becomes part of the raw SQL string. This allows an unauthenticated remote attacker to break out of the intended query context and inject arbitrary SQL clauses. The attacker can enumerate schema, exfiltrate credentials, modify records, or invoke stored procedures depending on database privileges.
Root Cause
The root cause is improper neutralization of special elements in a SQL command [CWE-89]. Parameters bound through the RecordStateMapper.xml mapper are inserted into the executed statement without input validation, escaping, or use of prepared-statement placeholders. Any request path that reaches this mapper propagates untrusted data directly into the SQL engine.
Attack Vector
Exploitation requires only network access to the Crocus application. No authentication or user interaction is needed. The attacker sends a crafted HTTP request containing SQL metacharacters in a parameter processed by RecordStateMapper.xml. A public proof-of-concept is available in the GitHub SQL Injection PoC repository, which documents the vulnerable parameter and payload structure. Because the injection reaches a mapper that handles record state operations, attackers can craft payloads such as UNION SELECT statements to read sensitive columns or boolean-based blind queries to extract data byte by byte.
Detection Methods for CVE-2026-52470
Indicators of Compromise
- HTTP requests to Crocus endpoints containing SQL metacharacters such as ', --, UNION SELECT, OR 1=1, or SLEEP( in parameters bound to RecordStateMapper.xml.
- Database logs showing malformed queries, unusually long WHERE clauses, or unexpected UNION operations originating from the Crocus application account.
- Sudden creation of new administrative accounts or privilege changes in the Crocus database.
Detection Strategies
- Deploy web application firewall (WAF) signatures that flag SQL injection patterns targeting Crocus request paths.
- Enable SQL query logging on the backend database and alert on syntax errors or queries containing tautologies like 1=1.
- Correlate application access logs with database audit logs to identify parameter values that trigger anomalous query shapes.
Monitoring Recommendations
- Monitor outbound traffic from the Crocus host for unexpected data volumes that could indicate database exfiltration.
- Track authentication events and role changes in the Crocus database for unauthorized privilege escalation.
- Alert on repeated 500-series HTTP errors from Crocus endpoints, which often accompany SQL injection probing.
How to Mitigate CVE-2026-52470
Immediate Actions Required
- Restrict network access to Crocus v1.3.44 instances to trusted management networks until a fixed release is applied.
- Place the Crocus application behind a WAF configured with SQL injection rulesets.
- Reduce privileges of the database account used by Crocus to the minimum required for application function.
- Review database audit logs for evidence of prior exploitation against RecordStateMapper.xml-backed endpoints.
Patch Information
No vendor advisory or fixed version has been published in the NVD entry for CVE-2026-52470 at the time of writing. Refer to the GitHub SQL Injection PoC for technical detail and monitor the Crocus vendor channels for a patched release. Upgrade beyond version 1.3.44 as soon as a corrected build is available.
Workarounds
- Deploy virtual patching rules on a reverse proxy or WAF to block requests containing SQL metacharacters targeting the vulnerable parameter.
- Rewrite affected mapper statements to use parameterized #{} placeholders instead of ${} string substitution if source-level modification is feasible.
- Isolate the Crocus database on a dedicated instance with no shared credentials so that a compromise cannot pivot to other systems.
