CVE-2026-115824

high

Description

Starman versions before 0.4019 for Perl allow memory exhaustion via unbounded buffering of chunked request bodies. The chunked body decoder keeps each chunk in memory until the whole chunk and its CRLF have arrived, and sets no limit on the length of a chunk-size line. A client that declares a huge chunk size and streams data, or sends a chunk-size line that never ends, grows the buffer for as long as it keeps sending. A remote attacker can exhaust worker memory with a single connection.
