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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"corazawaf","product":"coraza","versions":[{"version":">= 3.0.0, < 3.8.0","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N","baseScore":5.8,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":1.4}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-13T17:25:27.532169Z","id":"CVE-2026-41504","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-93"},{"lang":"en","value":"CWE-117"}]}],"references":[{"url":"https://github.com/corazawaf/coraza/commit/a3079325547c7c1e08522aed4d6468f25d080e25","source":"security-advisories@github.com"},{"url":"https://github.com/corazawaf/coraza/releases/tag/v3.8.0","source":"security-advisories@github.com"},{"url":"https://github.com/corazawaf/coraza/security/advisories/GHSA-prpw-wwv7-xjjr","source":"security-advisories@github.com"},{"url":"https://github.com/corazawaf/coraza/security/advisories/GHSA-prpw-wwv7-xjjr","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}]}
