What is CVE-2026-105107?
The Koha Integrated Library System is susceptible to SQL injection through its Most-circulated items report, allowing an authenticated user with proper permissions to execute arbitrary SQL commands. The vulnerability arises from the improper handling of user-controlled input in the reports/cat_issues_top.pl script, leading to seamless injection of malicious SQL into the database. This can result in unauthorized access to sensitive information, including user personal data and hash passwords. Mitigations have been introduced in later versions, including fixes in Koha 24.11.19, 25.05.14, 25.11.08, and 26.05.03.
