HIGH 7.5

DescriptionCVE.org

Svelte devalue is a JavaScript library that serializes values into strings when JSON.stringify isn't sufficient for the job. From 5.1.0 to 5.6.1, 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. This vulnerability is fixed in 5.6.2.

AnalysisAI

Denial of service in Svelte devalue library versions 5.1.0 through 5.6.1 allows remote attackers to exhaust CPU and memory resources by supplying malformed input to the parse function, affecting applications that process untrusted serialized data. The vulnerability stems from insufficient validation of ArrayBuffer inputs during deserialization. Applications should upgrade to version 5.6.2 or later.
