Summary
A stored SQL injection vulnerability in Koha (through 24.11.17, 25.05.12, 25.11.06, and 26.05.01) allows authenticated staff with the tools => items_batchmod permission to read arbitrary database contents by storing a SQL payload in the agefield value of an automatic item modification rule. The value is stored verbatim and later interpolated without parameterization into a SQL query in C4::Items::ToggleNewStatus when the scheduled cron job executes. The injection allows reading the entire Koha database including patron PII and staff bcrypt password hashes.
Risk Assessment
Authenticated staff can access the entire database, including sensitive information, potentially leading to severe security breaches.
Recommendation
Update Koha to a version newer than 26.05.01 or apply a patch that parameterizes SQL queries.
Original NVD description (English source)
A stored SQL injection vulnerability in Koha through 24.11.17, 25.05.12, 25.11.06, and 26.05.01 allows authenticated staff with the tools => items_batchmod permission to read arbitrary database contents by storing a SQL payload in the agefield value of an automatic item modification rule. The agefield value is stored verbatim to the system preference and later interpolated without parameterization into a SQL query in C4::Items::ToggleNewStatus (line 1228) when the scheduled cron job executes. The injection is SELECT-only under standard MariaDB/MySQL DBI single-statement execution; a time-based SLEEP payload is also achievable via the cron trigger. An attacker can read the entire Koha database including patron PII and staff bcrypt password hashes.
