In the world of web development, Joomla remains a popular choice for building dynamic websites. However, like any complex software, extensions can sometimes introduce security risks. A significant vulnerability has been discovered in the Regular Labs Modules Anywhere Pro extension for Joomla, identified as CVE-2026-100750. This high-severity flaw could expose websites to serious risks like Local File Inclusion (LFI) and Server-Side Request Forgery (SSRF), allowing attackers to potentially access sensitive data or make unauthorized requests.
Understanding the Threat
The Modules Anywhere Pro extension for Joomla, designed to allow flexible placement of modules, has a feature that enables additional attributes on a module tag to replace arbitrary parameters of the selected module. This feature is turned on by default in the affected versions. The main problem is that these parameter overrides are applied without verifying who created the content containing the module tag. This lack of proper authorization checks opens the door for malicious activity.
Specifically, the vulnerability creates pathways for:
- Local File Inclusion (LFI): An attacker could trick the system into opening and displaying local files from the server. This might expose sensitive configuration files, user data, or even system credentials.
- Server-Side Request Forgery (SSRF): This allows an attacker to make the server itself send requests to arbitrary network locations, including internal systems or other external websites. Depending on the server’s network access, an attacker could scan internal networks, access internal services, or even launch further attacks.
A concrete example highlighted in the vulnerability description involves Joomla’s core Feed module. Its rssurl parameter can be manipulated to accept not only regular network URLs but also local file: URLs, directly leading to LFI and SSRF exploitation.

Severity Level
With a CVSS score of 7.5, this vulnerability is rated as HIGH severity. This rating indicates that exploiting this flaw could have a significant impact, potentially leading to unauthorized access, information disclosure, or even system compromise. Due to the nature of LFI and SSRF, attackers could gain a foothold to further their malicious activities.
Possible Solutions
While specific patch versions were not explicitly detailed in the provided public information, the most critical step for users of Modules Anywhere Pro is to:
- Update Immediately: Check the official Regular Labs website (regularlabs.com) for the latest versions of the Modules Anywhere Pro extension. Vendors typically release patches or new versions that address reported vulnerabilities. It is highly probable that a version greater than 9.0.5 will contain the necessary fixes.
- Review Content Policies: Even after updating, ensure that only trusted content authors can create or modify content that uses module tags, especially if the vulnerability mitigations rely on such checks.
- Regular Backups: Always maintain regular backups of your website and database before performing any updates.
- Monitor Logs: Keep an eye on your server logs for any unusual activity that might indicate an attempted exploitation.
