CVE-2026-4276Network attack vector

Authenticated audit-log forgery via CRLF file identifier

Published Mar 16, 2026 · Updated Mar 16, 2026

Log injection in Danny Avila RAG API 0.7.0 allows remote authenticated users to forge audit entries through a crafted file_id. The ingestion routes write the form-data file_id value to application logs without neutralizing embedded carriage-return or line-feed characters. An authenticated file-ingestion request is required, and forged records can conceal activity or misdirect investigations; secondary attacks depend on an insecure downstream log viewer.
