Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-41115 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- kafka (Bitnami): affected from 4.0.0; fixed in 4.3.1\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-2026-41115/ (Markdown: https://insights.sbomify.com/CVE-2026-41115/index.md)","id":"CVE-2026-41115","markdown":"https://insights.sbomify.com/CVE-2026-41115/index.md","name":"CVE-2026-41115","record":{"aliases":["BIT-kafka-2026-41115","GHSA-p5r3-m3w4-4fj6","MINI-47f9-7442-wq3q","MINI-r8jv-vrwv-rf79"],"analysis":{"component_type":"server_software","fix_type":"configuration_change","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache Kafka","requires_auth":"low_privilege","summary":"Misconfigured ACLs in Apache Kafka allow unauthorized users to access sensitive consumer group metadata due to documentation discrepancies regarding required permissions.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"kafka","vendor":"apache"}],"cvss":{"score":4.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-285","name":"Improper Authorization"}],"description":"An improper authorization vulnerability has been identified in Apache Kafka.\n\nThe implementation of the CONSUMER_GROUP_DESCRIBE (69) API validates the DESCRIBE operation on the GROUP resource instead of the READ operation that documented in the official kafka documentation and the KIP-848. This discrepancy can result in misconfigured Access Control Lists (ACLs) and unintended security postures, like granting READ permission to users who should not be able to join/sync groups, or allowing users without READ permission (but with DESCRIBE permission) to access sensitive group metadata.\n\nThe correct permission for CONSUMER_GROUP_DESCRIBE API is DESCRIBE GROUP so the current implementation is correct. However, the kafka documentation as well as the KIP-848 will be updated to reflect the correct permission.
