CVE-2026-53781
Full vulnerability record from the local CVENow database.
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.

Atacantes que controlan una fuente de podcast o una URL de medios pueden transmitir una respuesta ilimitada al almacenamiento local a través de la ruta de descarga de archivos temporales, agotando los recursos de disco o del sistema en el host que ejecuta la CLI."
