Widget Factory Joomla Content Editor Improper Access Control Vulnerability

Widget Factory · Joomla Content Editor

CVSS 10 EPSS 83% no public exploit indexed Fix deadline passed 19 June 2026

What it is

Widget Factory Joomla Content Editor contains an improper access control vulnerability which could allow for upload and execution of PHP code via the creation of new editor profiles for unauthenticated users.

Why we say that

  • EPSS puts exploitation in the next 30 days at 83%
  • CISA's federal remediation deadline (2026-06-19) has passed
  • CVSS 10 critical
  • Listed in the CISA Known Exploited Vulnerabilities catalogue

Every line above comes from a named public source. Where the evidence is thin, we say so rather than inventing confidence — see methodology.

What to do

Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.

What it costs when this goes wrong
