Be the first to know when new zero-days emerge:

Summary

CVE-2026-48908 is a maximum-severity unauthenticated remote code execution (RCE) vulnerability in the SP Page Builder extension for Joomla, affecting all versions up to and including 6.6.1. A complete absence of authentication and file-type validation on the component’s icon-upload controller allows any unauthenticated remote attacker to upload an arbitrary PHP file to the web root and execute it immediately. The vulnerability carries a CVSS 4.0 score of 10.0 and is being actively exploited in the wild at the time of this publication.

Technical details

  • Root cause: The asset.uploadCustomIcon controller task in SP Page Builder performed no authentication or authorization checks and applied no server-side file-type validation, allowing unauthenticated HTTP requests to write arbitrary files—including PHP scripts—to web-accessible directories (CWE-284: Improper Access Control).
  • Trigger conditions: No authentication, special configuration, or user interaction is required. Any Joomla installation with SP Page Builder installed and enabled up to version 6.6.1 is vulnerable in its default state.
  • Attack vector: A remote, unauthenticated HTTP POST request to index.php?option=com_sppagebuilder&task=asset.uploadCustomIcon. The attack is fully automatable (CVSS 4.0 AU:Y) with no attack complexity (AC:L, AT:N).
  • Impact: Successful exploitation results in the upload and execution of PHP webshells, leading to full server compromise. Observed post-exploitation activity includes the creation of hidden Joomla Super Administrator accounts, deployment of persistent PHP file-manager backdoors under /media/com_sppagebuilder/assets/, and exposure of Joomla configuration files.

Affected software

  • SP Page Builder extension for Joomla, versions 1.0.0 through 6.6.1 (inclusive)

Severity

  • CVSS 4.0 Score: 10.0 (Critical)
  • CVSS 4.0 Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:A/AU:Y/U:Red
  • CWE: CWE-284 – Improper Access Control

Mitigation and recommended actions

  • Immediate action: Upgrade SP Page Builder to version 6.6.2 or later. Released June 14, 2026, version 6.6.2 gates the uploadCustomIcon controller behind an authenticated session, requires the user to hold admin or component-manage permission, and enforces a valid anti-CSRF token on the request.
  • If immediate upgrade is not possible: The vendor forum advisory notes that RsFirewall 3.3.7 includes a protective rule that mitigates exploitation of this vulnerability for sites unable to update immediately. Additionally, restricting external HTTP access to the Joomla administrator back-end at the network or web-server level reduces the attack surface while a maintenance window is arranged.
