An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-41187 in the wild and no public exploit code.\n\nAffected product: Tigera Calico. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-41187/ (Markdown: https://insights.sbomify.com/CVE-2026-41187/index.md)","id":"CVE-2026-41187","markdown":"https://insights.sbomify.com/CVE-2026-41187/index.md","name":"CVE-2026-41187","record":{"aliases":["GHSA-38w4-qxg9-xg36","MINI-3mmh-24jq-3q2c","MINI-7795-vxv8-gq89","MINI-7v2v-qpww-5x6r","MINI-gfjx-66hv-vmw9","MINI-jvgj-h44q-4mj3","MINI-qr34-xfp4-6374","MINI-x3j9-crg5-f7mv","MINI-xw89-rg86-cqgr"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"patch","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Calico network policy","requires_auth":"high_privilege","summary":"Attackers with deletecollection permissions can bypass tier authorization to bulk-delete network policies in unauthorized tiers, compromising network segmentation.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Tigera","cpe":[{"product":"calico","vendor":"tigera"}],"cvss":{"score":6.2,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:L/VA:L/SC:N/SI:L/SA:H","version":"4.0"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-285","name":"Improper Authorization"}],"description":"Calico's apiserver wraps tier-scoped resources so that every operation runs through AuthorizeTierOperation, but the Delete override on NetworkPolicy, GlobalNetworkPolicy, and their staged variants is not invoked for DeleteCollection requests.
