Internal service disclosure via unvalidated transcript fetch
Published Jun 11, 2026 · Updated Jun 11, 2026
SSRF in Summarize before 0.17.0 allows remote attackers controlling a podcast RSS feed to read internal service responses. The RSS transcript provider passes feed-controlled podcast:transcript URLs directly to fetch, follows redirects automatically, and neither resolves nor rejects private destinations first. The attack requires a user or daemon to process an attacker-controlled feed; successful requests can expose content from otherwise unreachable services.
