{"id":"CVE-2025-52890","aliases":["GHSA-p7fw-vjjm-2rwp","GO-2025-3782"],"url":"https://o3.security/vulnerability/CVE-2025-52890","summary":"Incus vulnerable to antispoofing nftables firewall rule bypass on bridge networks with ACLs","details":"Incus is a system container and virtual machine manager. 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.","published":"2025-06-25T16:51:24.279Z","modified":"2026-08-12T03:51:25.468853589Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:H"},"epss":{"score":0.00195,"percentile":0.09527,"asOf":"2026-08-18"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/lxc/incus/v6","fixedVersion":"6.14.0"}],"fix":{"url":"https://github.com/lxc/incus/commit/254dfd2483ab8de39b47c2258b7f1cf0759231c8","label":"lxc/incus@254dfd2"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/52xxx/CVE-2025-52890.json"},{"type":"ADVISORY","url":"https://github.com/lxc/incus/security/advisories/GHSA-p7fw-vjjm-2rwp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-52890"},{"type":"FIX","url":"https://github.com/lxc/incus/commit/254dfd2483ab8de39b47c2258b7f1cf0759231c8"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:25.468853589Z"}}
