CVSS 8.1 · High EPSS 0,51%

Kerentanan Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') pada n8n. Skor CVSS 3.1 8.1 (High) menurut NVD.

Deskripsi (NVD)

n8n before 1.123.67, 2.31.5, and 2.32.1 contains a prototype pollution vulnerability in the VM expression engine. An authenticated user able to create or edit a workflow expression can abuse the engine's array-element access to obtain a reference to a host built-in and pollute its prototype in the main n8n process (a sandbox escape), leading to a denial of service. Both self-hosted and cloud instances running the VM expression engine are affected.
