CVE-2026-0603
📋 TL;DR
A second-order SQL injection vulnerability in Hibernate's InlineIdsOrClauseBuilder allows remote attackers with low privileges to execute arbitrary SQL commands by providing specially crafted non-alphanumeric characters in ID columns. This can lead to sensitive information disclosure, data manipulation, or application-level denial of service. Applications using Hibernate with the vulnerable component are affected.
💻 Affected Systems
- Hibernate ORM
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including reading system files, data exfiltration, data destruction, and full application takeover leading to business disruption.
Likely Case
Sensitive data exposure from the application database, unauthorized data modification, and potential application downtime.
If Mitigated
Limited impact with proper input validation and parameterized queries in place, potentially only error generation.
🎯 Exploit Status
Requires attacker to have some level of application access and knowledge of vulnerable endpoints
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Red Hat advisory for specific patched versions
Vendor Advisory: https://access.redhat.com/security/cve/CVE-2026-0603
Restart Required: Yes
Instructions:
1. Review Red Hat advisory for affected versions. 2. Update Hibernate to patched version. 3. Restart application server. 4. Test application functionality.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation to reject non-alphanumeric characters in ID parameters
Use Parameterized Queries
allReplace InlineIdsOrClauseBuilder usage with parameterized queries or named parameters
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block SQL injection patterns
- Restrict database user permissions to minimum required for application functionality
🔍 How to Verify
Check if Vulnerable:
Check Hibernate version and review code for InlineIdsOrClauseBuilder usage with unsanitized user inputCheck Version:
Check application dependencies or pom.xml for Hibernate versionVerify Fix Applied:
Verify Hibernate version is updated to patched version and test vulnerable endpoints📡 Detection & Monitoring
Log Indicators:
- Unusual database query patterns
- SQL syntax errors in logs
- Multiple failed login attempts followed by complex queries
Network Indicators:
- Unusual database connection patterns
- Large data exfiltration
SIEM Query:
SELECT * FROM application_logs WHERE message LIKE '%SQL%' OR message LIKE '%database error%' AND severity='ERROR'
