{"cve":"CVE-2024-29834","nvd":{"published":"2024-04-02T20:15:09.607","modified":"2026-06-17T07:23:12.560","status":"Analyzed","description":"This vulnerability allows authenticated users with produce or consume permissions to perform unauthorized operations on partitioned topics, such as unloading topics and triggering compaction. These management operations should be restricted to users with the tenant admin role or superuser role. An authenticated user with produce permission can create subscriptions and update subscription properties on partitioned topics, even though this should be limited to users with consume permissions. This impact analysis assumes that Pulsar has been configured with the default authorization provider. For custom authorization providers, the impact could be slightly different. Additionally, the vulnerability allows an authenticated user to read, create, modify, and delete namespace properties in any namespace in any tenant. In Pulsar, namespace properties are reserved for user provided metadata about the namespace.\n\nThis issue affects Apache Pulsar versions from 2.7.1 to 2.10.6, from 2.11.0 to 2.11.4, from 3.0.0 to 3.0.3, from 3.1.0 to 3.1.3, and from 3.2.0 to 3.2.1. \n\n3.0 Apache Pulsar users should upgrade to at least 3.0.4.\n3.1 and 3.2 Apache Pulsar users should upgrade to at least 3.2.2.\n\nUsers operating versions prior to those listed above should upgrade to the aforementioned patched versions or newer versions.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4},"cwes":["CWE-863"],"references":["http://www.openwall.com/lists/oss-security/2024/04/02/2","https://lists.apache.org/thread/v0ltl94k9lg28qfr1f54hpkvvsjc5bj5","https://pulsar.apache.org/security/CVE-2024-29834/","http://www.openwall.com/lists/oss-security/2024/04/02/2","https://lists.apache.org/thread/v0ltl94k9lg28qfr1f54hpkvvsjc5bj5"],"products":["apache:pulsar"],"source":"nvd","synced_at":"2026-10-19T21:47:51.568503435+00:00"},"epss":{"cve":"CVE-2024-29834","score":0.01359,"percentile":0.71704,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-7mg2-6c6v-342r","url":"https://osv.dev/vulnerability/GHSA-7mg2-6c6v-342r","summary":"Apache Pulsar: Improper Authorization For Namespace and Topic Management Endpoints","modified":"2024-05-02T19:03:49.413269Z","packages":[{"ecosystem":"Maven","name":"org.apache.pulsar:pulsar-broker","purl":"pkg:maven/org.apache.pulsar/pulsar-broker","ranges":[">=2.7.1 <=2.10.6"],"fixed":[]},{"ecosystem":"Maven","name":"org.apache.pulsar:pulsar-broker","purl":"pkg:maven/org.apache.pulsar/pulsar-broker","ranges":[">=2.11.0 <=2.11.4"],"fixed":[]},{"ecosystem":"Maven","name":"org.apache.pulsar:pulsar-broker","purl":"pkg:maven/org.apache.pulsar/pulsar-broker","ranges":[">=3.0.0 <3.0.4"],"fixed":["3.0.4"]},{"ecosystem":"Maven","name":"org.apache.pulsar:pulsar-broker","purl":"pkg:maven/org.apache.pulsar/pulsar-broker","ranges":[">=3.1.0 <=3.1.3"],"fixed":[]},{"ecosystem":"Maven","name":"org.apache.pulsar:pulsar-broker","purl":"pkg:maven/org.apache.pulsar/pulsar-broker","ranges":[">=3.2.0 <3.2.2"],"fixed":["3.2.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
