A guide on how to do this is available in the release notes of 2.8.6.\n\nCredit: This issue was discovered by K."}],"metrics":{"cvssMetricV31":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":5.9}]},"weaknesses":[{"source":"security@apache.org","type":"Secondary","description":[{"lang":"en","value":"CWE-502"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:apache:storm:*:*:*:*:*:*:*:*","versionStartIncluding":"2.0.0","versionEndExcluding":"2.8.6","matchCriteriaId":"52FAF08F-1AE5-4EC5-BBA7-393B88FC8AD1"}]}]}],"references":[{"url":"https://storm.apache.org/2026/04/12/storm286-released.html","source":"security@apache.org","tags":["Release Notes","Vendor Advisory"]},{"url":"http://www.openwall.com/lists/oss-security/2026/04/12/6","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Mailing List","Third Party Advisory"]}]}}]}
