Summary
Missing CSRF protection in the execute_tool action in admin/ai.php in Emlog 2.6.26 and earlier allows a remote unauthenticated attacker to submit a forged request to a logged-in administrator. The attack can read all database tables and write to all tables except blog, including taking over an administrator account.
Risk Assessment
Risk of full administrator account takeover and access to sensitive data in Emlog.
Recommendation
Apply patches immediately or temporarily disable the AI Assistant feature until an official fix is available.
Original NVD description (English source)
Emlog is an open source website building system. In 2.6.26 and earlier, missing CSRF protection on the AI Assistant execute_tool action in admin/ai.php lets a remote unauthenticated attacker submit a forged cross-site request from an attacker-controlled page to a recently logged-in administrator. The authentication cookie set in include/lib/loginauth.php has no explicit SameSite attribute, enabling Chrome's temporary Lax+POST grace window. The query_database case passes attacker-controlled sql and confirm_code values to Ai::queryDatabase in include/service/ai.php; read queries need no confirmation, write queries accept the public confirm string, only the blog table is write-protected, and aliasing password as pwd_hash bypasses output redaction. A successful request can read every database table and write every table except blog, including changing the user table to take over an administrator account. No fixed version is available as of this review.
