Description
Summarize before 0.17.0 contains a server-side request forgery vulnerability that allows attackers who control a podcast RSS feed to direct the host to fetch transcript content from loopback addresses, link-local addresses, RFC 1918 private ranges, or other reserved destinations by supplying malicious podcast:transcript URL values. Attackers can bypass protections through DNS rebinding and redirect-based techniques, as redirect targets are not revalidated and hostnames are not resolved before request dispatch, exposing internal service responses through the summarization flow.
