Description
DBIx::QuickORM versions before 0.000026 for Perl allow SQL injection via unquoted SQL identifiers.
The default SQL builder, a SQL::Abstract subclass, sets bindtype in its constructor but never quote_char, so SQL::Abstract emits identifiers verbatim. Caller-supplied identifiers (order_by, where-clause column keys, field and returning lists, upsert columns, and join aliases) reach the SQL string raw, while values are placeholder-bound and unaffected.
A caller that forwards untrusted input to an affected identifier position, such as a user-controlled order_by value, enables SQL injection: the row order can be made to depend on a sub-select over columns the query never selected, and the where and update identifier positions permit further data disclosure and tampering.
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-2026-13766 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-2026-13766 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-2026-13766. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2026-13766 in your dependencies?
O3 detects CVE-2026-13766 across dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
