Devalue is vulnerable to denial of service due to memory exhaustion in devalue.parse

發布日:2026/1/15修改日:2026/2/3

描述

## Summary Certain inputs can cause `devalue.parse` to consume excessive CPU time and/or memory, potentially leading to denial of service in systems that parse input from untrusted sources. This affects applications using `devalue.parse` on externally-supplied data. The root cause is the typed array hydration expecting an `ArrayBuffer` as input, but not checking the assumption before creating the typed array. ## Details The parser's typed array hydration logic does not properly validate input before processing. Specially crafted inputs can cause disproportionate memory allocation or CPU usage on the receiving system. ## Impact This is a denial of service vulnerability affecting systems that use `devalue.parse` to handle data from potentially untrusted sources. Affected systems should upgrade to patched versions immediately.
