Loading vulnerability details...
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 ArrayBuffer hydration expecting base64 encoded strings as input, but not checking the assumption before decoding the input.
The parser's ArrayBuffer hydration logic does not properly validate input before processing. Specially crafted inputs can cause disproportionate memory allocation or CPU usage on the receiving system.
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.
