Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-33590 in the wild and no public exploit code.\n\nAffected product: Portainer Community Edition. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-33590/ (Markdown: https://insights.sbomify.com/CVE-2026-33590/index.md)","id":"CVE-2026-33590","markdown":"https://insights.sbomify.com/CVE-2026-33590/index.md","name":"CVE-2026-33590","record":{"aliases":["GHSA-frhv-529m-5v9v"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"configuration_change","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Portainer CE","requires_auth":"low_privilege","summary":"Authenticated non-admin users can exploit insecure default permissions in Portainer CE to read host files and execute code with root privileges.","user_interaction":"required","vuln_class":"misconfiguration"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ENISA","cpe":[],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:P","version":"4.0"},"cwes":[{"id":"CWE-276","name":"Incorrect Default Permissions"}],"description":"Insecure default settings of Portainer CE grant regular (non-admin) users privileges that allow host filesystem access and host-level code execution.
