CVE-2026-53781

Description

Summarize before 0.17.0 contains a resource exhaustion vulnerability that allows remote attackers to cause disk exhaustion by serving media responses that bypass the enforced size limit through missing or misreported Content-Length headers, chunked transfer encoding, or failed HEAD requests. Attackers who control a podcast feed or media URL can stream an unbounded response to local storage via the temp-file download path, exhausting disk or system resources on the host running the CLI.
