Security readout for executives and security teams
Plain-English summary
A flaw in Fabrik for Joomla could let an unauthenticated internet user manipulate database queries through a list-sorting parameter. Successful exploitation may expose or alter sensitive data and disrupt the application. Fabrik versions 1.0.0 through 4.7.1 are identified as affected.
Executive priority
Act immediately on internet-facing affected systems and rapidly inventory internal deployments. The technical severity is critical, but the supplied evidence does not confirm exploitation in the wild. Prioritize exposure reduction, supported upgrades, log preservation, and compromise review.
Technical view
CVE-2026-76602 is a CWE-89 SQL injection in Fabrik list models. The order parameter reaches SQL ORDER BY queries without validation, enabling read-oriented SQL injection vectors. The supplied CVSS 4.0 score is 9.3, reflecting remote, low-complexity, unauthenticated exploitation without user interaction and potentially high confidentiality, integrity, and availability impact.
Likely exposure
Internet-accessible Joomla sites running Fabrik 1.0.0 through 4.7.1 are the primary concern, particularly where list functionality is publicly reachable. Actual exposure depends on deployed versions, enabled components, routing, and whether vulnerable list requests reach the database.
Exploitation context
The supplied sources do not establish active exploitation, public proof-of-concept availability, or CISA KEV inclusion. Exploitation is nevertheless described as remotely reachable, unauthenticated, and low complexity. Treat exposed affected installations as urgent while distinguishing theoretical risk from confirmed compromise.
Researcher notes
The record identifies unsanitized use of order in list-model queries and describes read SQL injection vectors. The CVSS assessment indicates broader potential impact, but the bundle provides no code-level advisory, patch diff, exploit evidence, or indicators of compromise. Version-specific validation should rely on vendor materials and controlled defensive testing.
Mitigation direction
- Inventory Joomla installations and identify every deployed Fabrik version.
- Prioritize upgrading affected installations to Fabrik 4.7.2 or later, after confirming vendor guidance.
- Restrict public access to affected list functionality until remediation is verified.
- Review vendor guidance for additional mitigations or release-specific requirements.
- Preserve relevant web, application, and database logs before making changes.
Validation and detection
- Confirm Fabrik versions from deployment records and installed extension metadata.
- Map publicly reachable Fabrik list routes and their authentication requirements.
- Review logs for unusual order parameters, database errors, or anomalous list requests.
- Verify the installed release is 4.7.2 or later after remediation.
- Retest affected list sorting safely without using destructive or exploitative payloads.

Improper Neutralization of Special Elements used in an SQL Command
Improper Neutralization of Special Elements used in an SQL Command represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
