CVE-2026-70372· NVD / CVE Program· CNA TuranSec

Koha - SQL Injection in reports/bor_issues_top.pl

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. 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.

Weakness class (CWE)

CWE-89 · Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

CVSS vector

Root cause

The query text is built by concatenating user input. The database cannot tell where the data ends and the command begins.
