Prompt injection could cause the service to retrieve an attacker-chosen URL and potentially introduce content into downstream processing.<\/p>\n<p>The relevant capability is network access from the service, rather than access from a user\u2019s browser. Review which destinations the application can reach and whether untrusted input can influence retrieval.<\/p>\n<p>The advisory identifies 0.0.329 as the historical fixed version. Update affected legacy dependencies to a supported patched release. As a separate defensive measure, restrict outbound access where the application does not need it.
