{"id":"CVE-2026-22775","summary":"devalue vulnerable to denial of service due to memory/CPU exhaustion in devalue.parse","details":"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.","aliases":["GHSA-g2pg-6438-jwpf"],"modified":"2026-08-12T03:51:19.680380217Z","published":"2026-01-15T18:59:37.499Z","database_specific":{"cwe_ids":["CWE-405"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/22xxx/CVE-2026-22775.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/sveltejs/devalue/releases/tag/v5.6.2"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-22775.json"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:2144"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:2926"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-22775"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/22xxx/CVE-2026-22775.json"},{"type":"ADVISORY","url":"https://github.com/sveltejs/devalue/security/advisories/GHSA-g2pg-6438-jwpf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-22775"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2430109"},{"type":"FIX","url":"https://github.com/sveltejs/devalue/commit/11755849fa0634ae294a15ec0aef2f43efcad7c4"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/sveltejs/devalue","events":[{"introduced":"293d70bb7a3312741c370c8989fff0b5525647de"},{"fixed":"fcf4e88275f2e2e45b9ea70ffaa5247c8f55f057"},{"fixed":"11755849fa0634ae294a15ec0aef2f43efcad7c4"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:svelte:devalue:*:*:*:*:*:node.js:*:*","extracted_events":[{"introduced":"5.1.0"},{"fixed":"5.6.2"}]}}],"versions":["v5.6.1","v5.6.0","v5.5.0","v5.4.2","v5.4.1","v5.4.0","v5.3.2","v5.3.1","v5.3.0","v5.1.1","v5.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-22775.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
