FKIE_CVE-2026-70372

Vulnerability from fkie_nvd - Published: 2026-08-04 13:18 - Updated: 2026-08-04 18:16
Severity
6.5 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Summary
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.
