4Description
A flaw in Node.js Permission Model network enforcement leaves Unix Domain Socket (UDS) server operations without the required permission checks, while all comparable network paths correctly enforce them. As a result, code running under `--permission` without `--allow-net` can create and expose local IPC endpoints, allowing communication with other processes on the same host outside of the intended network restriction boundary. This vulnerability affects Node.js **25.x** processes using the Permission Model where `--allow-net` is intentionally omitted to restrict network access. Note that `--allow-net` is currently an experimental feature.
Analysis
Unix Domain Socket operations in Node.js 25.x bypass permission model enforcement, allowing local processes to create IPC endpoints and communicate with other processes when run with --permission flag but without --allow-net. An authenticated local attacker can establish inter-process communication channels that circumvent the intended network isolation boundary, resulting in information disclosure and potential privilege escalation within the same host. …
