CVE-2026-53782 Details
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.
A server-side request forgery (SSRF) vulnerability has been identified in the Steipete Summarize application, specifically in versions prior to 0.17.0. This vulnerability allows attackers who control a podcast RSS feed to manipulate the application into fetching transcript content from internal or reserved addresses, such as loopback addresses, link-local addresses, RFC 1918 private ranges, or other reserved destinations. The exploitation is achieved by supplying malicious podcast:transcript URL values, which can bypass existing protections through DNS rebinding and redirect-based techniques. The application's failure to properly validate and recheck redirect targets before processing requests exposes sensitive internal service responses during the summarization process.
Users can update to Steipete Summarize version 0.17.1 or later, where this vulnerability has been fixed.
