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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":5.3},"cwes":["CWE-400","CWE-772"],"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"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-107834","score":0.00322,"percentile":0.25004,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-rp9v-7xv3-r6g3","url":"https://osv.dev/vulnerability/GHSA-rp9v-7xv3-r6g3","summary":"Coraza: Resource exhaustion via deferred file handle accumulation in multipart body processor","modified":"2026-10-19T21:41:16.115574313Z","packages":[{"ecosystem":"Go","name":"github.com/corazawaf/coraza/v3","purl":"pkg:golang/github.com/corazawaf/coraza/v3","ranges":[">=3.0.0 <3.8.0"],"fixed":["3.8.0"]}]},{"id":"GO-2026-6697","url":"https://osv.dev/vulnerability/GO-2026-6697","summary":"Coraza: Resource exhaustion via deferred file handle accumulation in multipart body processor in github.com/corazawaf/coraza","modified":"2026-10-19T21:41:16.115574313Z","packages":[{"ecosystem":"Go","name":"github.com/corazawaf/coraza","purl":"pkg:golang/github.com/corazawaf/coraza","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/corazawaf/coraza/v2","purl":"pkg:golang/github.com/corazawaf/coraza/v2","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/corazawaf/coraza/v3","purl":"pkg:golang/github.com/corazawaf/coraza/v3","ranges":[">=3.0.0 <3.8.0"],"fixed":["3.8.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
