CyberRota Analysis
AI-GeneratedThe vulnerability affects the @hapi/content library, specifically in its handling of HTTP Content-* headers prior to version 6.0.2, where it improperly retains duplicate parameters. This flaw can lead to parameter-smuggling attacks, allowing an attacker to bypass upload filename allowlists, potentially enabling malicious file uploads. Organizations using affected versions of this library should prioritize updating to version 6.0.2 to mitigate the risk of exploitation.

Original NVD Description
@hapi/content provided HTTP Content-* headers parsing. Prior to 6.0.2, Content.disposition() retained the last occurrence of each duplicate parameter while Content.type() retained the first occurrence of duplicate charset and boundary parameters, creating a parameter-smuggling primitive when another component in the request-processing chain resolves duplicates the opposite way. This can allow an upload filename allowlist bypass in headers such as Content-Disposition: form-data; name="file"; filename="safe.txt"; filename="shell.php". This issue is fixed in version 6.0.2.
