CVE-2026-54511: Rfc5424 Syslog Sd Value Incomplete Escape
RFC 5424 structured data escaping only replaces backslashes, double quotes, and closing brackets, but does not sanitize C0 control characters (0x00-0x1F) such as newlines. In syslog framing (RFC 6587), unescaped newlines can terminate frames and allow log injection or frame forgery. Ensure all control characters are neutralized.
