When using an ACL on a device connected to a bridge, Incus versions 6.12 and 6.13generates nftables rules that partially bypass security options `security.mac_filtering`, `security.ipv4_filtering` and `security.ipv6_filtering`. This can lead to ARP spoofing on the bridge and to fully spoof another VM/container on the same bridge. Commit 254dfd2483ab8de39b47c2258b7f1cf0759231c8 contains a patch for the issue.\n\ud83d\udccf Published: 2025-06-25T16:51:24.279Z\n\ud83d\udccf Modified: 2025-06-25T16:51:24.279Z\n\ud83d\udd17 References:\n1. https://github.com/lxc/incus/security/advisories/GHSA-p7fw-vjjm-2rwp\n2. https://github.com/lxc/incus/commit/254dfd2483ab8de39b47c2258b7f1cf0759231c8", "creation_timestamp": "2025-06-25T18:06:28.000000Z"}
