CVE-2026-22775 - devalue vulnerable to denial of service due to memory/CPU exhaustion in devalue.parse
CVE ID : CVE-2026-22775
Published : Jan. 15, 2026, 7:16 p.m. | 1 hour, 11 minutes ago
Description : 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.
Severity: 7.5 | HIGH
