Description
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.
