Keeping your website secure is a constant effort, and for those using the popular Joomla content management system, staying on top of extension vulnerabilities is key. Recently, a Cross-Site Request Forgery (CSRF) vulnerability was identified in the Event Gallery extension by svenbluege.de, affecting its backend cleanup actions. This flaw, tracked as CVE-2026-100749, has a ‘Medium’ severity rating and highlights the importance of timely updates.
The Event Gallery extension for Joomla!, developed by svenbluege.de, was found to have a security flaw. This vulnerability, known as Cross-Site Request Forgery (CSRF), specifically impacts the backend cleanup operations. Essentially, an attacker could potentially trick an administrator into unknowingly performing actions like deleting old file entries or shopping carts. This could disrupt the integrity of your gallery data.
CVE Details
- Product Name: Joomla Event Gallery (svenbluege.de)
- Published: September 27, 2026
- Severity: Medium
- Status: Analyzed
Affected Products
Users running the Event Gallery extension for Joomla! are affected if they are using any version prior to 6.5.0. This includes both the Core and Extended editions of the extension.
Current Status
A patch for this vulnerability has been officially released by the developer. The latest available versions, such as Event Gallery Core 6.6.0 and Event Gallery Extended 6.6.0, address the identified CSRF flaw. This means a solution is readily available for users to implement.
Severity Level
A “Medium” severity rating indicates that this vulnerability could have a noticeable impact if exploited. While it doesn’t grant full control over your website, a successful CSRF attack could lead to unauthorized data manipulation. For instance, an attacker could craft a malicious link or embed code on a seemingly harmless page. If an authenticated administrator of the Joomla site visits this page, their browser might automatically send a request to the Event Gallery backend, triggering unintended cleanup actions. This could result in the deletion of orphaned file entries or shopping carts that are over 30 days old, potentially causing administrative headaches and data discrepancies.
Possible Solutions
To safeguard your Joomla installation and the Event Gallery content, it is critically important to update the extension without delay. This particular vulnerability is present in versions prior to 6.5.0. The good news is that the vendor, svenbluege.de, has already released a patched version. Based on information from their official website, Event Gallery Core 6.6.0 and Event Gallery Extended 6.6.0 are currently available. We strongly recommend upgrading your Event Gallery installation to version 6.5.0 or a newer release like 6.6.0. Always follow the official update procedures provided by svenbluege.de and ensure you back up your website before performing any updates. Regular updates to both your Joomla core and all installed extensions are your first line of defense against such web vulnerabilities.
