CVE-2026-107834
mediumOWASP Coraza WAF is a golang modsecurity compatible web application firewall library.
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.
