Denial Of Service (DoS)

Svelte devalue is vulnerable to a Denial-Of-Service DoS. The vulnerability is due to missing input validation during typed array hydration, where devalue.parse assumes an ArrayBuffer input without verification, allowing crafted inputs to trigger excessive CPU or memory consumption when parsing...

CVE-2026-22774

CVE-2026-22774 affects the Svelte devalue library. From versions 5.3.0 through 5.6.1, certain inputs trigger devalue.parse to consume excessive CPU time and memory when processing untrusted data, potentially causing denial of service. Root cause: typed array hydration assumes an ArrayBuffer input...

CVE-2026-22774 devalue vulnerable to denial of service due to memory exhaustion in devalue.parse

Svelte devalue is a JavaScript library that serializes values into strings when JSON.stringify isn't sufficient for the job. From 5.3.0 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 inpu...

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

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...

Svelte security vulnerabilities

Svelte is an open-source approach to building web applications. Versions of Svelte from 5.3.0 to 5.6.1 have security vulnerabilities. These vulnerabilities stem from the type array hydration process not checking input assumptions properly, which can lead to denial-of-service attacks...
