n8n before 2.43.5 and 2.44.x before 2.44.1 accepts a client-supplied workflow ID and caches each workflow's owner project in memory by that ID, so a crafted ID such as __proto__ makes the Data Table project check match every project. An authenticated member who can create and run workflows can list, read, modify, and delete Data Table rows in all projects of the instance.

CVE-2026-1235684.4 MÉD—
———Sveltejs devalue before 5.6.3 contains a prototype pollution vulnerability that allows attackers to alter object prototypes by supplying untrusted data to uneval. When the generated code is later evaluated, it creates objects with polluted prototypes, producing output data whose shape differs from the original input.9hCVE-2026-1235673.7 BAI—
———Sveltejs devalue before 5.6.4 contains a prototype injection vulnerability that allows attackers to inject __proto__ own properties into objects returned by devalue.parse and devalue.unflatten. Attackers can supply crafted serialized input that, when downstream code merges results via Object.assign, alters the target object's prototype.9hCVE-2026-1235613.7 BAI—
———devalue before 5.9.3 allows malformed null-prototype object keys to bypass parse's __proto__ rejection through property-key coercion, an incomplete fix for GHSA-mwv9-gp5h-frr4. Attackers can supply crafted payloads that yield objects with a __proto__ own property, which alone does not cause prototype pollution.9hCVE-2026-1061444.1 MÉD11.4%
——3Prototype Pollution in the Scheduler component (@progress/kendo-angular-scheduler and @progress/kendo-angular-common) in Progress Software Kendo UI for Angular versions prior to 25.1.0 allows a high-privileged attacker who can control a field path processed by the Scheduler to modify the prototype of built-in objects, resulting in a limited impact on confidentiality, integrity, and availability.2dCVE-2026-1061284.1 MÉD11.4%
——3Prototype Pollution in @progress/kendo-vue-common in Progress Software Kendo UI for Vue versions 0.4.0 through 9.2.0 allows a high-privileged attacker who can control a field path processed by components such as the Scheduler to modify the prototype of built-in objects, resulting in a limited impact on confidentiality, integrity, and availability.2dCVE-2026-1061274.1 MÉD11.4%
——3Prototype Pollution in the setter utility (@progress/kendo-react-common) in Progress Software KendoReact versions 3.5.0 through 16.0.0 allows a high-privileged attacker who can control a field path passed to the utility, directly or through components such as the Form, Scheduler, and Gantt, to modify the prototype of built-in objects, resulting in a limited impact on confidentiality, integrity, and availability.2d
