CVE-2026-21711 - Node.js Permission Model UDS Server Local IPC Exfiltration
CVE ID :CVE-2026-21711
Published : March 30, 2026, 8:16 p.m. | 49 minutes ago
Description :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.
Severity: 5.3 | MEDIUM
