Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-41726 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.springframework.kafka:spring-kafka (Maven): affected all versions up to 2.8.11; no fix listed\n- org.springframework.kafka:spring-kafka (Maven): affected all versions up to 2.8.11; no fix listed\n- org.springframework.kafka:spring-kafka (Maven): affected from 2.9.0 up to 2.9.13; no fix listed\n- org.springframework.kafka:spring-kafka (Maven): affected from 2.9.0 up to 2.9.13; no fix listed\n- org.springframework.kafka:spring-kafka (Maven): affected from 3.2.0 up to 3.2.13; no fix listed\n- org.springframework.kafka:spring-kafka (Maven): affected from 3.2.0 up to 3.2.13; no fix listed\n- org.springframework.kafka:spring-kafka (Maven): affected from 3.3.0; fixed in 3.3.16\n- org.springframework.kafka:spring-kafka (Maven): affected from 3.3.0; fixed in 3.3.16\n- org.springframework.kafka:spring-kafka (Maven): affected from 4.0.0; fixed in 4.0.6\n- org.springframework.kafka:spring-kafka (Maven): affected from 4.0.0; fixed in 4.0.6\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-2026-41726/ (Markdown: https://insights.sbomify.com/CVE-2026-41726/index.md)","id":"CVE-2026-41726","markdown":"https://insights.sbomify.com/CVE-2026-41726/index.md","name":"CVE-2026-41726","record":{"aliases":["GHSA-xvfq-4q6q-gxx7","MINI-7qxh-4v87-x89x","MINI-qc59-jcqj-grfh","ROOT-APP-MAVEN-CVE-2026-41726"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Spring Kafka library","requires_auth":"low_privilege","summary":"Attackers can cause denial of service via memory exhaustion in Spring for Apache Kafka when DelegatingDeserializer is enabled.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[{"product":"spring_for_apache_kafka","vendor":"vmware"}],"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-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"When an application opts into DelegatingDeserializer, a producer can grow the consumer's heap without bound by sending records with unique random spring.kafka.serialization.selector header values, eventually causing GC thrash and OutOfMemoryError.\n\nAffected versions:\nSpring for Apache Kafka 4.0.0 through 4.0.5;
