This flaw may surprise the application and cause it to misbehave and either send off the wrong data or use memory after free or similar in the subsequent `POST` request. The problem exists in the logic for a reused handle when it is changed from a PUT to a POST.","published":"2022-12-05T22:15:10.000Z","lastModified":"2026-10-14T17:17:40.000Z","status":"Modified","sourceIdentifier":"support@hackerone.com","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-200","CWE-668"],"affected":["haxx/curl","netapp/clustered data ontap","netapp/h300s firmware","netapp/h500s firmware","netapp/h700s firmware","netapp/h410s firmware","debian/debian linux","apple/macos","splunk/universal forwarder"],"epss":{"score":0.05092,"percentile":0.92301,"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 (5.09%).
