Detailsinfo

A vulnerability was found in Miyagawa Starman up to 0.4018. It has been declared as problematic. This vulnerability affects some unknown processing of the component Chunked Body Decoder. The manipulation with an unknown input leads to a memory allocation vulnerability. The CWE definition for the vulnerability is CWE-789. The product allocates memory based on an untrusted, large size value, but it does not ensure that the size is within expected limits, allowing arbitrary amounts of memory to be allocated. As an impact it is known to affect availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability was named CVE-2026-115824 since 10/23/2026. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are neither technical details nor an exploit publicly available.

Upgrading to version 0.4019 eliminates this vulnerability.
