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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5},"cwes":["CWE-20"],"references":["https://lists.apache.org/thread/ghs9jtjfbpy4c6xcftyvkl6swznlom1v","https://lists.apache.org/thread/ghs9jtjfbpy4c6xcftyvkl6swznlom1v"],"products":["apache:pulsar"],"source":"nvd","synced_at":"2026-10-19T21:36:05.460296998+00:00"},"epss":{"cve":"CVE-2022-24280","score":0.01451,"percentile":0.7339,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-3mg9-m3f6-v7fq","url":"https://osv.dev/vulnerability/GHSA-3mg9-m3f6-v7fq","summary":"Proxy component of Apache Pulsar subject to abuse as Denial of Service endpoint","modified":"2023-11-08T04:08:30.312432Z","packages":[{"ecosystem":"Maven","name":"org.apache.pulsar:pulsar","purl":"pkg:maven/org.apache.pulsar/pulsar","ranges":["<2.7.5"],"fixed":["2.7.5"]},{"ecosystem":"Maven","name":"org.apache.pulsar:pulsar","purl":"pkg:maven/org.apache.pulsar/pulsar","ranges":[">=2.8.0 <2.8.3"],"fixed":["2.8.3"]},{"ecosystem":"Maven","name":"org.apache.pulsar:pulsar","purl":"pkg:maven/org.apache.pulsar/pulsar","ranges":[">=2.9.0 <2.9.2"],"fixed":["2.9.2"]}]}],"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).
