Security readout for executives and security teams
Plain-English summary
Page Builder CK for Joomla contains a critical SQL injection flaw that could let an unauthenticated remote attacker compromise application data and availability. Installations running versions 1.0.0 through 3.6.4 require urgent attention. Version 3.6.4 addressed the frontend vector, while 3.6.5 addressed the backend vector.
Executive priority
Treat as an urgent remediation item because exploitation requires no authentication and may affect sensitive data, integrity, and service availability. Establish affected-asset scope immediately, upgrade promptly, and investigate exposed systems for suspicious activity. Current sources do not establish active exploitation.
Technical view
CVE-2026-74254 is a CWE-89 SQL injection in Page Builder CK’s styles model. CVSS 4.0 rates it 9.3: network-accessible, low complexity, no privileges or user interaction, with potentially high confidentiality, integrity, and availability impact. The supplied record identifies 3.6.5 as the first version addressing both described vectors.
Likely exposure
Exposure is highest on network-reachable Joomla sites using Page Builder CK versions 1.0.0 through 3.6.4. The supplied sources do not identify configuration prerequisites, affected endpoints, deployment prevalence, or whether protective controls reliably block exploitation.
Exploitation context
The CVSS vector indicates remote, unauthenticated exploitation without user interaction. However, the supplied sources provide no evidence of active exploitation, public proof-of-concept code, or inclusion in CISA KEV; the bundle explicitly reports KEV as false.
Researcher notes
The record distinguishes two remediation points: 3.6.4 fixed the frontend vector, while 3.6.5 fixed the backend. Consequently, 3.6.4 remains within the stated affected range. No endpoint details, root-cause analysis, patch diff, exploit evidence, or compensating-control guidance are supplied.
Mitigation direction
- Inventory Joomla installations and identify every deployed Page Builder CK version.
- Upgrade affected installations to version 3.6.5 or later, following vendor guidance.
- Prioritize internet-facing and business-critical Joomla systems.
- Restrict unnecessary access until upgrades are completed if operationally feasible.
- Preserve relevant application, database, and security logs for investigation.
Validation and detection
- Confirm Page Builder CK is absent or reports version 3.6.5 or later.
- Check frontend and administrative deployments rather than assuming version 3.6.4 is fully fixed.
- Review logs for unusual styles-model requests, database errors, or unexplained data changes.
- Verify application and database integrity after remediation.
- Use safe, authorized vulnerability validation without destructive SQL injection testing.

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.
