It is expected that users of the CORS filter will have configured it appropriately for their environment rather than using it in the default configuration. Therefore, it is expected that most users will not be impacted by this issue.","published":"2018-05-16T16:29:00.000Z","lastModified":"2026-10-15T18:17:21.000Z","status":"Modified","sourceIdentifier":"security@apache.org","cvss":{"version":"3.0","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-1188"],"affected":["apache/tomcat","canonical/ubuntu linux","debian/debian linux","netapp/oncommand insight","netapp/oncommand unified manager","netapp/oncommand workflow automation","netapp/snapcenter server","netapp/storage automation store"],"epss":{"score":0.20942,"percentile":0.97547,"date":"2026-10-27","history":[{"date":"2026-09-21","score":0.19436,"percentile":0.97302},{"date":"2026-09-22","score":0.21313,"percentile":0.97488}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 20.9%, higher than 98% of all known CVEs.
