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-2026-100707 exists.\n\nAffected packages and fixed versions:\n- kyverno (Bitnami): affected all versions; fixed in 1.19.1\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-2026-100707/ (Markdown: https://insights.sbomify.com/CVE-2026-100707/index.md)","id":"CVE-2026-100707","markdown":"https://insights.sbomify.com/CVE-2026-100707/index.md","name":"CVE-2026-100707","record":{"aliases":["BIT-kyverno-2026-100707","GHSA-66wc-m66q-pf76","GHSA-c5qq-7g2q-cpqp","MINI-2x67-frr5-6657","MINI-39mw-xcpf-9wh9","MINI-84vm-hjwj-2v45","MINI-8fvg-hcpg-f3pj","MINI-95rg-hh79-hc5v","MINI-98f2-cgjc-pc5r","MINI-c2v4-gr2m-3xg2","MINI-c92j-q2ch-j7fw","MINI-f395-f2j8-gf2q","MINI-h4qw-9f3r-r2qr","MINI-hmv5-39gf-rjwc","MINI-p3hv-pq96-fmxf","MINI-vxcf-h783-9wcq"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Kubernetes policy engine","requires_auth":"low_privilege","summary":"Low-privilege tenants can bypass namespace isolation via percent-encoded paths to read cross-namespace resources using Kyverno's service account.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Kyverno before 1.19.1 contains a namespace isolation bypass in the apiCall context entry of namespaced Policy resources due to inconsistent path interpretation between validation and execution.
