Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-87106 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- consul (Bitnami): affected from 1.21.0; fixed in 2.0.4\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-2026-87106/ (Markdown: https://insights.sbomify.com/CVE-2026-87106/index.md)","id":"CVE-2026-87106","markdown":"https://insights.sbomify.com/CVE-2026-87106/index.md","name":"CVE-2026-87106","record":{"aliases":["BIT-consul-2026-87106","GHSA-q5mw-fjrj-6qmh","MINI-h774-6233-mc2m","MINI-v96g-cppw-w8wj","UBUNTU-CVE-2026-87106"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Service mesh and discovery","requires_auth":"low_privilege","summary":"Authenticated clients can exhaust server memory in Consul's RPC listener before ACL checks, causing denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"HashiCorp","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Consul and Consul Enterprise are vulnerable to a denial of service in the native RPC listener that may allow an authenticated client to exhaust server memory before ACL authorization is evaluated.
