Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-36782 exists.\n\nAffected packages and fixed versions:\n- github.com/rancher/rancher (Go): affected from 2.5.0; fixed in 2.5.16\n- github.com/rancher/rancher (Go): affected from 2.5.0; fixed in 2.5.16\n- github.com/rancher/rancher (Go): affected from 2.6.0; fixed in 2.6.7\n- github.com/rancher/rancher (Go): affected from 2.6.0; fixed in 2.6.7\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-2021-36782/ (Markdown: https://insights.sbomify.com/CVE-2021-36782/index.md)","id":"CVE-2021-36782","markdown":"https://insights.sbomify.com/CVE-2021-36782/index.md","name":"CVE-2021-36782","record":{"aliases":["GHSA-g7j7-h4q8-8w2f"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Rancher Kubernetes management","requires_auth":"low_privilege","summary":"Authenticated users can retrieve plaintext sensitive credentials via the Kubernetes API, exposing secrets to unauthorized parties.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"suse","cpe":[{"product":"rancher","vendor":"suse"}],"cvss":{"score":9.9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-312","name":"Cleartext Storage of Sensitive Information"}],"description":"A Cleartext Storage of Sensitive Information vulnerability in SUSE Rancher allows authenticated Cluster Owners, Cluster Members, Project Owners, Project Members and User Base to use the Kubernetes API to retrieve plaintext version of sensitive data.
