CVE-2026-71288

HIGHCVSS 8.8/10EPSS 0.25%

Last modified

CVE-2026-71288 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. 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.. EPSS estimates a 0.25% chance of exploitation in the next 30 days.
