CVE-2026-71245
HIGHCVE-2026-71245 is a high-severity (CVSS 7.1) SQL Injection vulnerability. O3 Security confirms whether CVE-2026-71245 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
Mautic's getLeadIdsByFieldValueAction (LeadBundle/Controller/AjaxController.php) reads a field parameter from the request, sanitizes it only with InputHelper::clean() (which HTML-entity-encodes quotes and angle brackets but does not restrict other characters), and passes it into LeadRepository::buildQueryForGetLeadsByFieldValue() where it is concatenated directly as a raw SQL column identifier ($col = 'l.'.$field) rather than being validated against a whitelist of real column names or passed as a bound parameter. Since Doctrine cannot parameterize identifiers, and the sanitizer does not block spaces, parentheses, or other SQL-relevant characters, an attacker can inject SQL via the field name itself. The action requires only a valid session (any authenticated user), unlike sibling actions in the same controller that carry additional permission checks.
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-2026-71245 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-2026-71245 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-2026-71245. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
