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.","published_at":"2026-01-15T18:59:37.499000Z","last_modified_at":null,"cvss_v3_score":7.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-405"],"nvd_references":["https://github.com/sveltejs/devalue/security/advisories/GHSA-g2pg-6438-jwpf","https://github.com/sveltejs/devalue/commit/11755849fa0634ae294a15ec0aef2f43efcad7c4","https://github.com/sveltejs/devalue/releases/tag/v5.6.2"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:29:11.897956Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"N","value_label":"None"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"sveltejs","vendor_name":"sveltejs","product_slug":"devalue","product_name":"devalue","version_start":">= 5.1.0, < 5.6.2","version_start_inclusive":true,"version_end":">= 5.1.0, < 5.6.2","version_end_inclusive":true,"cpe23_uri":"cve5:sveltejs:devalue:>= 5.1.0, < 5.6.2:>= 5.1.0, < 5.6.2"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/sveltejs/devalue/security/advisories/GHSA-g2pg-6438-jwpf","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/sveltejs/devalue/commit/11755849fa0634ae294a15ec0aef2f43efcad7c4","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/sveltejs/devalue/releases/tag/v5.6.2","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-01-15T18:59:37.499000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:51:39.184495Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:51:39.184495Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:51:39.184495Z","label":"CVSS score revised","source":"cvelistv5"}]}
