CVE-2026-70372
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.
No public exploitation has been reported so far. No distribution fix is listed yet; apply vendor mitigations and monitor.
Recommended action: Track your distribution's security tracker and apply the fix as soon as it ships.
Affected & fixed versions by distribution
Versions are the native distribution strings (backport-aware): RHEL/Debian/SUSE backport fixes, so compare with the distro version comparator (dpkg / rpm / vercmp), not the upstream version.
No affected package in the tracked watchlist yet (Debian, Ubuntu, Arch, SUSE, Red Hat...). Triage may still be pending.
