OPNsense Root RCE Flaw CVE-2026-57155 (CVSS 9.9): Details and PoC Publicly Disclosed
TL;DR A researcher from Hacking Cult published full technical details and proof-of-concept code for three OPNsense firewall flaws. The worst, CVE-2026-57155 (CVSS 9.9), escalates a low-privileged account into a full OPNsense root RCE. OPNsense fixed all three issues in versions 26.1.11 and 26.4.1p1. Why It Matters OPNsense guards the network edge for many homes and businesses. So a root bug on the firewall hands an attacker the whole perimeter.
