{"id":"CVE-2026-107834","published":"2026-10-09T18:17:05.007","lastModified":"2026-10-13T21:17:32.713","description":"OWASP Coraza WAF is a golang modsecurity compatible web application firewall library. From 3.0.0 until 3.8.0, the multipart loop in internal/bodyprocessors/multipart.go executes defer temp.Close() for every uploaded file part, so each temporary-file descriptor remains open until the complete request returns. An unauthenticated attacker can submit a multipart body containing many minimal file parts and exhaust the process file-descriptor table within the request-body size limit, causing os.CreateTemp failures, MULTIPART_STRICT_ERROR responses, blocked legitimate uploads, and process-wide inability to open files or sockets. This issue is fixed in version 3.8.0.","cvssScore":5.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","cwes":["CWE-400","CWE-772"],"vendors":[],"products":[],"references":[{"url":"https://github.com/corazawaf/coraza/commit/1bc39036e99c88e7de60cf8e6bb55ee4c311223c","tags":[]},{"url":"https://github.com/corazawaf/coraza/releases/tag/v3.8.0","tags":[]},{"url":"https://github.com/corazawaf/coraza/security/advisories/GHSA-rp9v-7xv3-r6g3","tags":[]}],"exploitRefs":[{"url":"https://github.com/corazawaf/coraza/commit/1bc39036e99c88e7de60cf8e6bb55ee4c311223c","tags":[]},{"url":"https://github.com/corazawaf/coraza/releases/tag/v3.8.0","tags":[]},{"url":"https://github.com/corazawaf/coraza/security/advisories/GHSA-rp9v-7xv3-r6g3","tags":[]}],"hasPoc":true,"ai":null}
