Security readout for executives and security teams
Plain-English summary
SP Page Builder versions 1.0.0 through 6.7.0 contain a critical database injection flaw. An unauthenticated internet user may exploit improperly checked sorting parameters in Dynamic Content requests to expose sensitive database information. The available evidence does not indicate data modification or service disruption.
Executive priority
Treat this as an immediate remediation priority for internet-facing sites. The flaw needs no authentication or user action and may expose sensitive database information. Identify affected installations promptly, upgrade them, and investigate suspicious requests. Internal or isolated systems should follow after externally reachable instances.
Technical view
CVE-2026-65766 is a CWE-89 SQL injection caused by improper validation of order parameters in SP Page Builder’s Dynamic Content endpoint. CVSS 4.0 rates it 9.2: network-accessible, low complexity, requiring no privileges or user interaction, with high confidentiality impact but no stated integrity or availability impact.
Likely exposure
Joomla sites running SP Page Builder 1.0.0 through 6.7.0 are affected, particularly where the Dynamic Content endpoint is remotely reachable. The supplied sources do not identify configuration prerequisites, the precise endpoint path, or whether every installation enables the vulnerable functionality.
Exploitation context
The vulnerability is not listed as a CISA KEV in the supplied record, and no cited source establishes active exploitation. Its unauthenticated, network-accessible, low-complexity characteristics nevertheless make exposed installations attractive targets. No exploit instructions or proof-of-concept details are included here.
Researcher notes
The record identifies improper validation of Dynamic Content order parameters but does not disclose the exact route, query construction, database-specific behavior, or demonstrated extraction scope. CVSS indicates high vulnerable-system and subsequent-system confidentiality impact, with no stated integrity or availability impact. Avoid inferring broader compromise without supporting evidence.
Mitigation direction
- Upgrade SP Page Builder to version 6.7.1 or a later vendor-supported release.
- Prioritize internet-facing Joomla installations and systems containing sensitive database information.
- Review JoomShaper guidance for any additional configuration changes or compensating controls.
- Restrict unnecessary access to affected functionality until upgrading is complete.
Validation and detection
- Inventory Joomla sites and confirm the installed SP Page Builder version.
- Verify no production instance remains on versions 1.0.0 through 6.7.0.
- Confirm the deployed extension reports version 6.7.1 or later after remediation.
- Review web and security logs for suspicious Dynamic Content requests involving order parameters.
- Monitor vendor and CVE updates for newly documented exploitation indicators or prerequisites.

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