Summary
CVE-2026-67285 is an unauthenticated local file inclusion (LFI) vulnerability in the SP Page Builder extension for Joomla, caused by improper limitation of a pathname to a restricted directory (CWE-22). The flaw allows a remote, unauthenticated attacker to force the component to include arbitrary local PHP files accessible on the server. It carries a CVSS v4.0 base score of 9.2 (Critical), reflecting the fact that no credentials or user interaction are required to exploit it over the network.
Technical details
- Root cause: SP Page Builder fails to properly sanitize/restrict a path parameter used when including PHP files, allowing path traversal (CWE-22).
- Trigger conditions: No authentication is required; the vulnerable functionality is reachable by any remote, unauthenticated user.
- Attack vector: Network (AV:N), low attack complexity (AC:L), requiring attack requirements to be met (AT:P), but no privileges (PR:N) or user interaction (UI:N).
- Impact: High impact to confidentiality, integrity, and availability (VC:H/VI:H/VA:H) — inclusion of arbitrary local PHP files can be leveraged to disclose sensitive files or, where an attacker can influence file content on disk, to achieve remote code execution.
Affected software
- SP Page Builder extension for Joomla (joomshaper.com), versions 1.0.0 through 6.7.1.
- Fixed in version 6.8.0.
Severity
- CVSS v4.0 Base Score: 9.2 (Critical)
- Vector:
CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
Mitigation and recommended actions
- Immediate: Upgrade SP Page Builder to version 6.8.0 or later, where the file inclusion issue is remediated.
- If no patch can be applied immediately: Restrict public network access to the Joomla site’s SP Page Builder endpoints where feasible, and deploy a WAF rule to block path traversal sequences (e.g.,
../, encoded traversal patterns) in requests targeting the component. - Review web server and application logs for anomalous file-include requests or attempts to reference PHP files outside expected component paths.
