When the Apache Pulsar Proxy component is used, it is possible to attempt to open TCP/IP connections to any IP address and port that the Pulsar Proxy can connect to. An attacker could use this as a way for DoS attacks that originate from the Pulsar Proxy's IP address. It hasn’t been detected that the Pulsar Proxy authentication can be bypassed. The attacker will have to have a valid token to a properly secured Pulsar Proxy. This issue affects Apache Pulsar Proxy versions 2.7.0 to 2.7.4; 2.8.0 to 2.8.2; 2.9.0 to 2.9.1; 2.6.4 and earlier.","published_at":"2022-09-23T09:25:12Z","last_modified_at":null,"cvss_v3_score":6.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":"none","ssvc_automatable":false,"ssvc_technical_impact":"partial","cwes":["CWE-20"],"nvd_references":["https://lists.apache.org/thread/ghs9jtjfbpy4c6xcftyvkl6swznlom1v"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-29T00:58:50.406025Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"N","value_label":"None"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"apache-software-foundation","vendor_name":"Apache Software Foundation","product_slug":"apache-pulsar","product_name":"Apache Pulsar","version_start":"2.7","version_start_inclusive":true,"version_end":"2.7.4","version_end_inclusive":true,"cpe23_uri":"cve5:apache-software-foundation:apache-pulsar:2.7:2.7.4"},{"vendor_slug":"apache-software-foundation","vendor_name":"Apache Software Foundation","product_slug":"apache-pulsar","product_name":"Apache Pulsar","version_start":"2.8","version_start_inclusive":true,"version_end":"2.8.2","version_end_inclusive":true,"cpe23_uri":"cve5:apache-software-foundation:apache-pulsar:2.8:2.8.2"},{"vendor_slug":"apache-software-foundation","vendor_name":"Apache Software Foundation","product_slug":"apache-pulsar","product_name":"Apache Pulsar","version_start":"2.9","version_start_inclusive":true,"version_end":"2.9.1","version_end_inclusive":true,"cpe23_uri":"cve5:apache-software-foundation:apache-pulsar:2.9:2.9.1"},{"vendor_slug":"apache-software-foundation","vendor_name":"Apache Software Foundation","product_slug":"apache-pulsar","product_name":"Apache Pulsar","version_start":"2.6 and earlier","version_start_inclusive":true,"version_end":"2.6.4","version_end_inclusive":true,"cpe23_uri":"cve5:apache-software-foundation:apache-pulsar:2.6 and earlier:2.6.4"}],"exploit_refs":[],"news":[],"references":[{"url":"https://lists.apache.org/thread/ghs9jtjfbpy4c6xcftyvkl6swznlom1v","source_type":"MAILING_LIST","tags":["mailing-list"]}],"timeline":[{"type":"published","at":"2022-09-23T09:25:12Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:21:31.961730Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:21:31.961730Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:21:31.961730Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"ssvc_changed","at":"2026-06-29T00:58:50.406025Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T00:58:50.406025Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T00:58:50.406025Z","label":"SSVC decision revised","source":"vulnrichment"}]}
