CVE-2026-71288

HIGH 8.8

Koha SQL Injection via order_by and {order}_ovalue Parameters in guided_reports.pl

CVSS Score

8.8

EPSS Score

0.0%

EPSS Percentile

0th

Koha's guided report builder (reports/guided_reports.pl) reads the CGI parameter and, for each value, a dynamically-named parameter, and concatenates both directly into an SQL ORDER BY clause with no allowlist or validation. Since ORDER BY columns cannot be bound via prepared-statement placeholders, this requires an explicit allowlist, which does not exist.
