Detailsinfo

A vulnerability was found in Koha Community Koha up to 24.11.16/25.05.11/25.11.5/26.05.0. It has been declared as problematic. Affected by this vulnerability is the function calculate of the file reports/bor_issues_top.pl of the component Reports Module. The manipulation of the argument Criteria/Filter/Limit with an unknown input leads to a sql injection vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Koha's reports/bor_issues_top.pl builds dynamic SQL in sub calculate by concatenating several user-controlled request parameters directly into the query string. The Criteria parameter is only normalized by a table-name prefix and is never whitelisted, landing verbatim in identifier positions (SELECT DISTINCTROW, GROUP BY, ORDER BY); Filter values are concatenated raw into single-quoted LIKE, BETWEEN, and comparison fragments, and the Limit parameter is appended raw to a LIMIT clause. 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.

It is possible to read the advisory at bugs.koha-community.org. This vulnerability is known as CVE-2026-70372 since 08/04/2026. The exploitation appears to be easy.
