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-2024-1023 exists.\n\nAffected packages and fixed versions:\n- io.vertx:vertx-core (Maven): affected from 4.4.5; fixed in 4.4.7\n- io.vertx:vertx-core (Maven): affected from 4.4.5; fixed in 4.4.7\n- io.vertx:vertx-core (Maven): affected from 4.5.0; fixed in 4.5.2\n- io.vertx:vertx-core (Maven): affected from 4.5.0; fixed in 4.5.2\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-2024-1023/ (Markdown: https://insights.sbomify.com/CVE-2024-1023/index.md)","id":"CVE-2024-1023","markdown":"https://insights.sbomify.com/CVE-2024-1023/index.md","name":"CVE-2024-1023","record":{"aliases":["GHSA-5667-3wch-7q7w"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java reactive toolkit","requires_auth":"low_privilege","summary":"Attackers can cause memory leaks in Vert.x HTTP clients by connecting to arbitrary hosts, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","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-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"A vulnerability in the Eclipse Vert.x toolkit results in a memory leak due to using Netty FastThreadLocal data structures.
