This flaw allows an HTTP(S)\nserver to overwrite an existing local file specified in the\n`Content-Disposition` header despite the presence of the `-J` non-overwrite\nconstraint.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://curl.se/docs/CVE-2026-92390.html","tags":[]},{"url":"https://curl.se/docs/CVE-2026-92390.json","tags":[]},{"url":"https://hackerone.com/reports/4023192","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
