{"cve":"CVE-2026-41504","nvd":{"published":"2026-10-12T21:17:17.080","modified":"2026-10-16T20:04:29.760","status":"Deferred","description":"OWASP Coraza WAF is a golang modsecurity compatible web application firewall library. From 3.0.0 until 3.8.0, the Native audit-log formatter in internal/auditlog/formats.go writes attacker-influenced request and response fields without neutralizing carriage returns or line feeds. When SecAuditLogFormat Native is enabled, injected line breaks can create forged lines inside a transaction record. An attacker who controls request or response body, header, error-message, or matched-rule data can inject carriage returns and line feeds that appear as forged audit lines within a transaction record. The forged content can mislead operators and line-oriented SIEM processing, although the unpredictable transaction boundary prevents straightforward impersonation of a separate complete session. 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:C/C:N/I:L/A:N","score":5.8},"cwes":["CWE-93","CWE-117"],"references":["https://github.com/corazawaf/coraza/commit/a3079325547c7c1e08522aed4d6468f25d080e25","https://github.com/corazawaf/coraza/releases/tag/v3.8.0","https://github.com/corazawaf/coraza/security/advisories/GHSA-prpw-wwv7-xjjr","https://github.com/corazawaf/coraza/security/advisories/GHSA-prpw-wwv7-xjjr"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:52.678897993+00:00"},"epss":{"cve":"CVE-2026-41504","score":0.00355,"percentile":0.28911,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-prpw-wwv7-xjjr","url":"https://osv.dev/vulnerability/GHSA-prpw-wwv7-xjjr","summary":"Coraza: Native audit-log format allows CRLF injection and log forgery via request body and header fields","modified":"2026-10-20T00:40:33.971199199Z","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-2026-6669","url":"https://osv.dev/vulnerability/GO-2026-6669","summary":"Coraza: Native audit-log format allows CRLF injection and log forgery via request body and header fields in github.com/corazawaf/coraza","modified":"2026-10-20T00:30:05.355003525Z","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).
