Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-41571 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.pulsar:pulsar (Maven): affected all versions up to 2.6.4; no fix listed\n- org.apache.pulsar:pulsar (Maven): affected all versions up to 2.6.4; no fix listed\n- org.apache.pulsar:pulsar (Maven): affected from 2.7.0; fixed in 2.7.4\n- org.apache.pulsar:pulsar (Maven): affected from 2.7.0; fixed in 2.7.4\n- org.apache.pulsar:pulsar (Maven): affected from 2.8.0; fixed in 2.8.1\n- org.apache.pulsar:pulsar (Maven): affected from 2.8.0; fixed in 2.8.1\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-2021-41571/ (Markdown: https://insights.sbomify.com/CVE-2021-41571/index.md)","id":"CVE-2021-41571","markdown":"https://insights.sbomify.com/CVE-2021-41571/index.md","name":"CVE-2021-41571","record":{"aliases":["GHSA-3whx-qrj5-hh2h"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Pulsar","requires_auth":"low_privilege","summary":"Authenticated users can read data from other tenants via the Admin API due to insufficient validation of ledger IDs against topic permissions.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"pulsar","vendor":"apache"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"In Apache Pulsar it is possible to access data from BookKeeper that does not belong to the topics accessible by the authenticated user. The Admin API get-message-by-id requires the user to input a topic and a ledger id. The ledger id is a pointer to the data, and it is supposed to be a valid it for the topic. Authorisation controls are performed against the topic name and there is not proper validation the that ledger id is valid in the context of such ledger. So it may happen that the user is able to read from a ledger that contains data owned by another tenant.
