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-2026-61672 exists.\n\nAffected packages and fixed versions:\n- github.com/projectcapsule/capsule (Go): affected all versions; fixed in 0.13.7\n- github.com/projectcapsule/capsule (Go): affected all versions; fixed in 0.13.7\n- github.com/projectcapsule/capsule (Go): affected all versions; fixed in 0.13.7\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-2026-61672/ (Markdown: https://insights.sbomify.com/CVE-2026-61672/index.md)","id":"CVE-2026-61672","markdown":"https://insights.sbomify.com/CVE-2026-61672/index.md","name":"CVE-2026-61672","record":{"aliases":["GHSA-gjw4-3v3v-rqxg","GO-2026-6520"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Kubernetes multi-tenancy framework","requires_auth":"low_privilege","summary":"Tenant owners can bypass Capsule's forbidden label and annotation enforcement due to a sorting bug, allowing them to violate cluster policies and tenant boundaries.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-697","name":"Incorrect Comparison"}],"description":"Capsule is a multi-tenancy and policy-based framework for Kubernetes. Prior to 0.13.7, ForbiddenListSpec.ExactMatch in pkg/api/forbidden_list.go sorts denied metadata keys case-insensitively and then uses sort.SearchStrings, which assumes byte-order sorting. When an administrator's forbidden list mixes capitalized and lowercase keys or otherwise has different case-insensitive and byte ordering, the binary search can return false for a key that is present. An authenticated tenant owner can then pass the missed key through api.ValidateForbidden and bypass configured namespace, Service, or delegated node metadata restrictions, potentially influencing cluster policies, network exposure, or scheduling outside the tenant boundary. Uniformly lowercase lists whose two orderings coincide are not affected.
