An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-23606 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- envoy (Bitnami): affected from 1.20.0; fixed in 1.20.2, 1.21.1\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-2022-23606/ (Markdown: https://insights.sbomify.com/CVE-2022-23606/index.md)","id":"CVE-2022-23606","markdown":"https://insights.sbomify.com/CVE-2022-23606/index.md","name":"CVE-2022-23606","record":{"aliases":["BIT-envoy-2022-23606","GHSA-9vp2-4cp7-vvxf"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Envoy proxy","requires_auth":"high_privilege","summary":"An attacker can crash the Envoy proxy by triggering infinite recursion during cluster deletion with many idle connections, causing denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"envoy","vendor":"envoyproxy"}],"cvss":{"score":4.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-674","name":"Uncontrolled Recursion"}],"description":"Envoy is an open source edge and service proxy, designed for cloud-native applications.
