CVE-2026-34228 is a Cross-Site Request Forgery (CSRF) vulnerability affecting Emlog CMS versions 1.0.0 through 2.6.8. This flaw allows an attacker to trick an authenticated administrator into executing malicious SQL code and writing arbitrary files to the web server's root directory. The vulnerability stems from the backend upgrade interface's lack of CSRF protection when handling remote SQL and ZIP URLs. A patch is available in version 2.6.8.
The impact of CVE-2026-34228 is significant. Successful exploitation allows an attacker to inject arbitrary SQL queries, potentially leading to data breaches, modification, or deletion. The ability to write files directly to the web root directory enables attackers to upload malicious code, such as web shells, granting them remote code execution (RCE) capabilities. This could result in complete compromise of the Emlog CMS instance and potentially the underlying server. The lack of CSRF protection makes this vulnerability relatively easy to exploit, as it only requires social engineering to lure an administrator to a malicious link.
CVE-2026-34228 was publicly disclosed on 2026-04-03. Currently, there are no known public proof-of-concept exploits available. The vulnerability is not listed on the CISA KEV catalog. Given the ease of exploitation and the potential for significant impact, it is recommended to prioritize patching.
Administrators of Emlog CMS installations running versions 1.0.0 through 2.6.8 are at significant risk. Shared hosting environments running Emlog are particularly vulnerable, as attackers could potentially compromise multiple websites from a single exploit. Users who have not implemented strong password policies or multi-factor authentication are also at increased risk of being targeted.
• php / web server:
grep -r 'remote_url=.*\.sql' /var/www/emlog/includes/upgrade.php
grep -r 'remote_url=.*\.zip' /var/www/emlog/includes/upgrade.php• web server:
# Check access logs for suspicious upgrade requests
grep "/wp-admin/upgrade.php?remote_url=" /var/log/apache2/access.log• generic web: Check for unusual files in the web root directory, particularly those with SQL or ZIP extensions.

The primary mitigation for CVE-2026-34228 is to immediately upgrade Emlog CMS to version 2.6.8 or later. If upgrading is not immediately feasible, consider implementing a temporary workaround by restricting access to the backend upgrade interface. This can be achieved through firewall rules or access control lists (ACLs) to limit access to only trusted administrators. Additionally, implement strict input validation and sanitization on all user-supplied data, particularly within the upgrade process. While not a direct fix, a Web Application Firewall (WAF) configured to block requests containing SQL or ZIP URLs in the GET parameters could provide some protection.
Aktualisieren Sie Emlog auf Version 2.6.8 oder höher, um die Schwachstelle zu beheben. Diese Version behebt das Fehlen der CSRF-Validierung in der Backend-Upgrade-Schnittstelle und verhindert so die Ausführung von Remote-SQL und die Dateischreibung.
