CVE-2026-116128— Starlet versions from 0.20 before 0.33 for Perl allow memory exhaustion via unbounded buffering when decoding chunked request bodies

Quick assessment

Affected
CVE-2026-116128
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Perl 语言中的 Starlet 框架从 0.20 版本到 0.33 版本之前，在解码分块（chunked）请求主体时，因无限制缓冲而导致内存耗尽漏洞。 该解码器将每次读取的数据追加到一个未消耗的输入缓冲区中。由于对分块大小（chunk-size）行的长度没有任何限制，若某行缺少 CRLF 终止符，只要客户端持续发送数据，该缓冲区就会不断增长；同时，每次读取操作后都会重置读取超时时间。此外，大分块的数据也会一直保留在缓冲区中，直到整个分块接收完毕。 远程攻击者仅需发送单个请求，即可耗尽工作进程（worker）的内

Vulnerability Description
Starlet versions from 0.20 before 0.33 for Perl allow memory exhaustion via unbounded buffering when decoding chunked request bodies. The decoder adds each read to one buffer of unconsumed input. Nothing limits the length of a chunk-size line, so a line without a CRLF grows the buffer for as long as the client keeps sending, and the read timeout restarts after every read. The data of a large chunk is also held in the buffer until the whole chunk has arrived. A remote attacker can exhaust a worker's memory with a single request.
