CVE-2026-27493
CriticalSummary
n8n to platforma automatyzacji procesów roboczych typu open source. Przed wersjami 2.10.1, 2.9.3 i 1.123.22 istniała podatność na drugorzędne wstrzykiwanie wyrażeń w węzłach formularzy, która mogła pozwolić nieautoryzowanemu atakującemu na wstrzykiwanie i ocenianie dowolnych wyrażeń n8n poprzez przesyłanie spreparowanych formularzy.
Risk Assessment
Podatność ta może umożliwić atakującym wykonanie nieautoryzowanych działań w systemie, co może prowadzić do poważnych naruszeń bezpieczeństwa danych i integralności aplikacji.
Recommendation
Zaleca się aktualizację n8n do najnowszych wersji, aby usunąć tę podatność oraz monitorowanie systemu pod kątem podejrzanej aktywności związanej z formularzami.

The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the _getObjAttr function in all versions up to, and including, 3.5.54. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). This requires the PDF Generator add-on to be active and a Contact Form 7 form to be configured for PDF generation.

- CVE-2026-94290Critical
The SUSE Rancher Fleet controller did not sufficiently restrict which kubeconfig secrets a Fleet Cluster object was allowed to reference. As a result, an ordinary user could define a cluster in a namespace they control and associate it with administrative credentials for the management cluster, causing the controller to manage the management cluster on that user's behalf with elevated privileges. This affects Fleet 0.16.0–0.16.3, 0.15.0–0.15.8, 0.14.0–0.14.12, 0.13.0–0.13.17 and possibly older versions.
