An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-65835 exists.\n\nAffected packages and fixed versions:\n- github.com/projectcapsule/capsule (Go): affected from 0.13.0; fixed in 0.13.8\n- github.com/projectcapsule/capsule (Go): affected from 0.13.0; fixed in 0.13.8\n- github.com/projectcapsule/capsule (Go): affected from 0.13.0; fixed in 0.13.8\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-2026-65835/ (Markdown: https://insights.sbomify.com/CVE-2026-65835/index.md)","id":"CVE-2026-65835","markdown":"https://insights.sbomify.com/CVE-2026-65835/index.md","name":"CVE-2026-65835","record":{"aliases":["GHSA-jr6p-8pjj-mfx6","GO-2026-6157"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Kubernetes multi-tenancy framework","requires_auth":"high_privilege","summary":"Tenant owners can escalate privileges to create cluster-scoped resources like ClusterRoles due to missing validation in Capsule's resource handling logic.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"Capsule is a multi-tenancy and policy-based framework for Kubernetes.
