CVE-2026-60027 Overview
CVE-2026-60027 is an unauthenticated path traversal vulnerability in the Quix Page Builder Pro extension for Joomla, developed by themexpert.com. Versions prior to 6.2.1 are affected. Attackers can exploit form elements on published pages to traverse the filesystem and read arbitrary files without authentication.
The flaw is classified under CWE-22 (Improper Limitation of a Pathname to a Restricted Directory). Exploitation requires only that the target site have a published page containing a Form element. Successful attacks disclose sensitive files, including configuration data and credentials stored on the web server.
Critical Impact
Unauthenticated attackers can read arbitrary files from vulnerable Joomla sites running Quix Page Builder Pro versions earlier than 6.2.1.
Affected Products
- ThemeXpert Quix Page Builder Pro (Joomla extension) versions prior to 6.2.1
- Joomla sites with at least one published page containing a Form element
- Any Joomla installation that has installed and enabled the vulnerable Quix Page Builder Pro extension

Technical Details for CVE-2026-60027
Vulnerability Analysis
The vulnerability resides in the form element handler of Quix Page Builder Pro. The extension processes user-supplied input tied to form elements without sanitizing directory traversal sequences. Attackers submit crafted parameters containing sequences such as ../ to escape the intended base directory.
Because the endpoint responsible for handling form data is exposed to unauthenticated frontend users, no login or session is required. The server reads the requested file and returns its contents to the attacker. This enables disclosure of Joomla configuration files, database credentials, private keys, and other sensitive resources readable by the web server process.
The CWE-22 classification confirms the root defect: absence of a canonicalization and allowlist check on file path input. Exploitation is reliable across affected installations because the attack targets a documented feature of the extension rather than an environment-specific edge case.
Root Cause
Quix Page Builder Pro accepts a filename or path parameter tied to form processing and passes it to a file read routine without validating that the resolved path stays within the intended directory. Missing input normalization and lack of a base-directory containment check allow relative path segments to reach the underlying filesystem call.
Attack Vector
The attack is network-based and requires no privileges or user interaction. An attacker locates a published page hosting a Form element, then issues an HTTP request to the associated form handler with a manipulated path parameter. The response contains the contents of the targeted file. The exploit is trivial to automate against Joomla sites indexed by search engines.
No verified public exploit code is available at this time. Refer to the ThemeXpert Quix PageBuilder overview for product context and vendor updates.
Detection Methods for CVE-2026-60027
Indicators of Compromise
- HTTP requests to Quix Page Builder form endpoints containing traversal sequences such as ../, ..%2f, or encoded variants in query or POST parameters
- Web server access logs showing unauthenticated reads returning contents of configuration.php, /etc/passwd, or other sensitive files
- Unusual response sizes from form submission endpoints on pages hosting Quix Form elements
Detection Strategies
- Inspect web server and reverse proxy logs for requests to Joomla component endpoints referencing com_quix combined with path traversal patterns
- Deploy WAF signatures that block directory traversal payloads targeting Joomla form submission routes
- Correlate frontend form POSTs with outbound responses larger than expected form acknowledgements
Monitoring Recommendations
- Enable verbose access logging on the Joomla frontend and forward events to a centralized SIEM for path traversal pattern matching
- Alert on any reads or exposures of configuration.php or files outside the Joomla web root reachable through the extension
- Track version metadata of installed Joomla extensions and flag any Quix Page Builder installation below 6.2.1
How to Mitigate CVE-2026-60027
Immediate Actions Required
- Upgrade Quix Page Builder Pro to version 6.2.1 or later on all Joomla installations
- Unpublish or remove pages containing Form elements until the upgrade is applied if immediate patching is not feasible
- Audit the web server for signs of prior arbitrary file reads and rotate any credentials stored in configuration.php
Patch Information
ThemeXpert addresses the flaw in Quix Page Builder Pro version 6.2.1. Administrators should download the current release from the vendor and apply it through the Joomla extension manager. Verify the installed version after upgrade to confirm remediation. See the ThemeXpert Quix PageBuilder page for release information.
Workarounds
- Temporarily disable the Quix Page Builder Pro extension through the Joomla administrator panel until patching is completed
- Restrict access to Joomla form endpoints using web server ACLs or a WAF rule that blocks path traversal payloads
- Move sensitive files outside the web root or tighten filesystem permissions on the web server user where feasible
