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.\nhttps://www.cve.org/CVERecord?id=CVE-2026-107834https://github.com/corazawaf/coraza/security/advisories/GHSA-rp9v-7xv3-r6g3https://github.com/corazawaf/coraza/commit/1bc39036e99c88e7de60cf8e6bb55ee4c311223chttps://github.com/corazawaf/coraza/releases/tag/v3.8.0#corazawaf #coraza#CVE_2026_107834#bot", "creation_timestamp": "2026-10-09T17:49:32.638287Z"}
