{"id":"CVE-2026-41504","published":"2026-10-12T21:17:17.080","lastModified":"2026-10-16T20:04:29.760","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.","cvssScore":5.8,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N","cwes":["CWE-93","CWE-117"],"vendors":[],"products":[],"references":[{"url":"https://github.com/corazawaf/coraza/commit/a3079325547c7c1e08522aed4d6468f25d080e25","tags":[]},{"url":"https://github.com/corazawaf/coraza/releases/tag/v3.8.0","tags":[]},{"url":"https://github.com/corazawaf/coraza/security/advisories/GHSA-prpw-wwv7-xjjr","tags":[]},{"url":"https://github.com/corazawaf/coraza/security/advisories/GHSA-prpw-wwv7-xjjr","tags":[]}],"exploitRefs":[{"url":"https://github.com/corazawaf/coraza/commit/a3079325547c7c1e08522aed4d6468f25d080e25","tags":[]},{"url":"https://github.com/corazawaf/coraza/releases/tag/v3.8.0","tags":[]},{"url":"https://github.com/corazawaf/coraza/security/advisories/GHSA-prpw-wwv7-xjjr","tags":[]},{"url":"https://github.com/corazawaf/coraza/security/advisories/GHSA-prpw-wwv7-xjjr","tags":[]}],"hasPoc":true,"ai":null}
