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.","state":0,"publishedAt":"2026-10-09T18:17:05.007+00:00","modifiedAt":"2026-10-16T17:16:41.3+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":5.3,"severity":"MEDIUM"}],"references":["https://github.com/corazawaf/coraza/commit/1bc39036e99c88e7de60cf8e6bb55ee4c311223c","https://github.com/corazawaf/coraza/releases/tag/v3.8.0","https://github.com/corazawaf/coraza/security/advisories/GHSA-rp9v-7xv3-r6g3"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-107834","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-400","CWE-772"],"productCriteria":[],"sourceDates":{"published":"2026-10-09T18:17:05.007","lastModified":"2026-10-16T17:16:41.300"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
