Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-pfhr-pccp-hwmh in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/cilium/cilium (Go): affected all versions; fixed in 1.10.14, 1.11.8, 1.12.1\n- github.com/cilium/cilium (Go): affected all versions; fixed in 1.10.14\n- github.com/cilium/cilium (Go): affected all versions; fixed in 1.10.14\n- github.com/cilium/cilium (Go): affected from 1.11.0; fixed in 1.11.8\n- github.com/cilium/cilium (Go): affected from 1.11.0; fixed in 1.11.8\n- github.com/cilium/cilium (Go): affected from 1.12.0; fixed in 1.12.1\n- github.com/cilium/cilium (Go): affected from 1.12.0; fixed in 1.12.1\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/GHSA-pfhr-pccp-hwmh/ (Markdown: https://insights.sbomify.com/GHSA-pfhr-pccp-hwmh/index.md)","id":"GHSA-pfhr-pccp-hwmh","markdown":"https://insights.sbomify.com/GHSA-pfhr-pccp-hwmh/index.md","name":"GHSA-pfhr-pccp-hwmh","record":{"aliases":["GO-2022-0959"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Cilium network policy","requires_auth":"low_privilege","summary":"Attackers with pod deploy rights can craft labels to bypass Cilium network policies, allowing unauthorized network access between pods.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"### Impact\n\nIf a user has Network Policies with namespace selectors selecting labels of namespaces, or (clusterwide) Cilium Network Policies matching on namespace labels, then it is possible for an attacker with Kubernetes pod deploy rights (either directly or indirectly via higher-level APIs such as Deployment, Daemonset etc) to craft additional pod labels such that the pod is selected by another policy that exists rather than the expected policy. \n\n### Patches\n\nThe problem has been fixed and is available on versions \u003e=1.10.14, \u003e=1.11.8, \u003e=1.12.1\n\n### Workarounds\n\nThere are no workarounds available.\n\n### Acknowledgements\n\nThe Cilium community has worked together with members of Isovalent to prepare these mitigations.
