Detailsinfo

A vulnerability, which was classified as problematic, was found in Koha Community Koha up to 24.11.16/25.05.11/25.11.5/26.05.0. Affected is the function calculate of the file reports/catalogue_stats.pl of the component Reports Module. The manipulation of the argument Line/Column with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Koha's reports/catalogue_stats.pl builds dynamic SQL in sub calculate by interpolating the user-controlled Line and Column request parameters directly into identifier positions of the query (SELECT DISTINCTROW, GROUP BY, ORDER BY) with no whitelist validation. When Line contains itemcallnumber and the cotedigits parameter is truthy, cotedigits is additionally concatenated raw as the numeric argument of a LEFT() call. An authenticated staff user holding the reports module permission can inject arbitrary SQL and read any table reachable by the Koha database user, including borrowers (password hashes, two-factor secrets, personal data), api_keys, and sessions.

The advisory is shared for download at bugs.koha-community.org. This vulnerability is traded as CVE-2026-70370 since 08/04/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. Additional levels of successful authentication are needed for exploitation. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1505.

Upgrading to version 24.11.17, 25.05.12, 25.11.06 or 26.05.01 eliminates this vulnerability.
