From 2.33.0 to before 2.33.8, 2.39.2, and 2.41.0, Portainer offers an environment-level Disable bind mounts for non-administrators security setting that blocks regular users from binding host paths into containers they create through the Portainer-mediated Docker API. The check that enforces this setting only inspected the legacy HostConfig.Binds array on the container-create proxy and never looked at the equivalent HostConfig.Mounts array. Any authenticated user with rights to create containers on a Docker environment where the restriction is enabled could submit a bind-typed entry under HostConfig.Mounts and mount any host path into their container. This vulnerability is fixed in 2.33.8, 2.39.2, and 2.41.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N","score":8.5},"cwes":["CWE-863"],"references":["https://github.com/portainer/portainer/security/advisories/GHSA-7fw3-x4r2-g7wc"],"products":["portainer:portainer"],"source":"nvd","synced_at":"2026-10-19T22:36:28.938604137+00:00"},"epss":{"cve":"CVE-2026-44850","score":0.00234,"percentile":0.14368,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-7fw3-x4r2-g7wc","url":"https://osv.dev/vulnerability/GHSA-7fw3-x4r2-g7wc","summary":"Portainer has a bind-mount restriction bypass via HostConfig.Mounts","modified":"2026-06-25T19:56:14.843796976Z","packages":[{"ecosystem":"Go","name":"github.com/portainer/portainer","purl":"pkg:golang/github.com/portainer/portainer","ranges":[">=2.33.0 <2.33.8"],"fixed":["2.33.8"]},{"ecosystem":"Go","name":"github.com/portainer/portainer","purl":"pkg:golang/github.com/portainer/portainer","ranges":[">=2.39.0 <2.39.2"],"fixed":["2.39.2"]},{"ecosystem":"Go","name":"github.com/portainer/portainer","purl":"pkg:golang/github.com/portainer/portainer","ranges":[">=2.40.0 <2.41.0"],"fixed":["2.41.0"]}]},{"id":"GO-2026-5217","url":"https://osv.dev/vulnerability/GO-2026-5217","summary":"Portainer has a bind-mount restriction bypass via HostConfig.Mounts in github.com/portainer/portainer","modified":"2026-06-25T19:45:16.783646632Z","packages":[{"ecosystem":"Go","name":"github.com/portainer/portainer","purl":"pkg:golang/github.com/portainer/portainer","ranges":["all versions"],"fixed":[]}]}],"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).
