Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-44884 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 2.39.1\n- github.com/portainer/portainer (Go): affected from 2.39.0; fixed in 2.39.1\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-2026-44884/ (Markdown: https://insights.sbomify.com/CVE-2026-44884/index.md)","id":"CVE-2026-44884","markdown":"https://insights.sbomify.com/CVE-2026-44884/index.md","name":"CVE-2026-44884","record":{"aliases":["GHSA-cqpq-2fgr-8mvc","GO-2026-5333"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Portainer container management","requires_auth":"low_privilege","summary":"Authenticated users can read any custom template file, potentially exposing sensitive credentials, due to missing authorization checks.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"portainer","vendor":"portainer"}],"cvss":{"score":6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-862","name":"Missing 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 and 2.39.1, a missing authorization vulnerability in the Custom Template file endpoint (GET /api/custom_templates/{id}/file) allows any authenticated user to read the file content of any custom template by enumerating sequential integer IDs, bypassing Resource Control access restrictions. Template files may contain environment-specific values such as connection strings, API tokens, or registry credentials that administrators would not expect standard users to read.
