CVE-2026-70370
CVE-2026-70370 is a SQL Injection vulnerability. O3 Security confirms whether CVE-2026-70370 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
Koha's reports/catalogue_stats.pl builds dynamic SQL in sub calculate by interpolating the user-controlled Line and Column request parameters directly into identifier positions of the query (SELECT DISTINCTROW, GROUP BY, ORDER BY) with no whitelist validation. When Line contains itemcallnumber and the cotedigits parameter is truthy, cotedigits is additionally concatenated raw as the numeric argument of a LEFT() call. 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.
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-2026-70370 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-2026-70370 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-2026-70370. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
