{"cve":"CVE-2025-54410","nvd":{"published":"2025-07-30T14:15:28.900","modified":"2026-06-17T09:40:02.927","status":"Analyzed","description":"Moby is an open source container framework developed by Docker Inc. that is distributed as Docker Engine, Mirantis Container Runtime, and various other downstream projects/products. A firewalld vulnerability affects Moby releases before 28.0.0. When firewalld reloads, Docker fails to re-create iptables rules that isolate bridge networks, allowing any container to access all ports on any other container across different bridge networks on the same host. This breaks network segmentation between containers that should be isolated, creating significant risk in multi-tenant environments. Only containers in --internal networks remain protected.\nWorkarounds include reloading firewalld and either restarting the docker daemon, re-creating bridge networks, or using rootless mode. Maintainers anticipate a fix for this issue in version 25.0.13.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":5.2},"cwes":["CWE-909"],"references":["https://firewalld.org/documentation/howto/reload-firewalld.html","https://github.com/moby/moby/security/advisories/GHSA-4vq8-7jfc-9cvp"],"products":["mobyproject:moby"],"source":"nvd","synced_at":"2026-10-19T22:05:46.678065081+00:00"},"epss":{"cve":"CVE-2025-54410","score":0.00177,"percentile":0.07239,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-4vq8-7jfc-9cvp","url":"https://osv.dev/vulnerability/GHSA-4vq8-7jfc-9cvp","summary":"Moby firewalld reload removes bridge network isolation","modified":"2026-09-10T03:50:25.738441655Z","packages":[{"ecosystem":"Go","name":"github.com/docker/docker","purl":"pkg:golang/github.com/docker/docker","ranges":["<25.0.13"],"fixed":["25.0.13"]},{"ecosystem":"Go","name":"github.com/docker/docker","purl":"pkg:golang/github.com/docker/docker","ranges":[">=26.0.0-rc1 <28.0.0"],"fixed":["28.0.0"]}]},{"id":"GO-2025-3829","url":"https://osv.dev/vulnerability/GO-2025-3829","summary":"Moby firewalld reload removes bridge network isolation in github.com/docker/docker","modified":"2026-02-04T02:16:52.930136Z","packages":[{"ecosystem":"Go","name":"github.com/docker/docker","purl":"pkg:golang/github.com/docker/docker","ranges":["<25.0.13+incompatible"],"fixed":["25.0.13+incompatible"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
