What is CVE-2026-71288?
CVE-2026-71288 is a high-severity SQL injection vulnerability in Koha, published on 5 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
