No affected components available
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.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the availability of the system.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
