The error handling triggered in this case could cause the a pooled object to be placed in the pool twice. This could result in subsequent connections using the same object concurrently which could result in data being returned to the wrong use and/or other errors.","published":"2022-05-13T08:15:07.000Z","lastModified":"2026-10-08T22:17:20.000Z","status":"Modified","sourceIdentifier":"security@apache.org","cvss":{"version":"3.1","score":8.6,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L"},"cwe":["CWE-404"],"affected":["apache/tomcat","oracle/agile product lifecycle management"],"epss":{"score":0.08405,"percentile":0.94949,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (8.40%).
