CVE-2026-71288
HIGHCVE-2026-71288 is a high-severity (CVSS 8.8) SQL Injection vulnerability. O3 Security confirms whether CVE-2026-71288 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
Koha's guided report builder (reports/guided_reports.pl) reads the order_by CGI parameter and, for each value, a dynamically-named {order}_ovalue parameter, and concatenates both directly into an SQL ORDER BY clause with no allowlist or validation: my @order_by = $input->multi_param('order_by'); foreach my $order (@order_by) { my $value = $input->param($order . "_ovalue"); $query_orderby = " ORDER BY $order $value"; }. The resulting string is appended verbatim to the final query in C4::Reports::Guided ($query .= $orderby;) with no escaping. Since ORDER BY columns cannot be bound via prepared-statement placeholders, this requires an explicit allowlist, which does not exist. Any staff account with the low-privilege create_reports or execute_reports permission (commonly granted to non-admin library staff) can perform time-based blind SQL injection against the Koha database, which stores patron PII and staff/LDAP credentials.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2026-71288 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-71288 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-71288. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
