Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-44850 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/portainer/portainer (Go): affected all versions; no fix listed\n- github.com/portainer/portainer (Go): affected from 2.33.0; fixed in 2.33.8\n- github.com/portainer/portainer (Go): affected from 2.33.0; fixed in 2.33.8\n- github.com/portainer/portainer (Go): affected from 2.39.0; fixed in 2.39.2\n- github.com/portainer/portainer (Go): affected from 2.39.0; fixed in 2.39.2\n- github.com/portainer/portainer (Go): affected from 2.40.0; fixed in 2.41.0\n- github.com/portainer/portainer (Go): affected from 2.40.0; fixed in 2.41.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-44850/ (Markdown: https://insights.sbomify.com/CVE-2026-44850/index.md)","id":"CVE-2026-44850","markdown":"https://insights.sbomify.com/CVE-2026-44850/index.md","name":"CVE-2026-44850","record":{"aliases":["GHSA-7fw3-x4r2-g7wc","GO-2026-5217"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["privilege_escalation","data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Container management platform","requires_auth":"low_privilege","summary":"Authenticated users can bypass bind-mount restrictions by using HostConfig.Mounts, allowing them to mount arbitrary host paths into containers.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"portainer","vendor":"portainer"}],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"Portainer Community Edition is a lightweight service delivery platform for containerized applications that can be used to manage Docker, Swarm, Kubernetes and ACI environments. 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.
