{"id":"GHSA-x5rw-q4pp-hg5g","aliases":[],"url":"https://o3.security/vulnerability/GHSA-x5rw-q4pp-hg5g","summary":"devalue: stringifyAsync can cause an unhandled rejection despite a caught returned promise","details":"When serializing multiple promises, a later promise can reject before an earlier one settles. An internal rejected promise remains unhandled even if the caller catches the returned `stringifyAsync` promise. Under Node's default unhandled-rejection behavior this can terminate the process. Applications whose asynchronous failures/timing can be influenced by requests are potentially exposed.\n\nThis is essentially impossible to exploit, and is much more likely to surface as a developer-introduced bug.","published":"2026-10-01T15:15:13Z","modified":"2026-10-01T15:30:10.729813749Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"devalue","fixedVersion":"5.9.3"}],"fix":{"url":"https://github.com/sveltejs/devalue/commit/dae8153e9d7541b975cc4018138d6cebec6c1199","label":"sveltejs/devalue@dae8153"},"references":[{"type":"WEB","url":"https://github.com/sveltejs/devalue/security/advisories/GHSA-x5rw-q4pp-hg5g"},{"type":"WEB","url":"https://github.com/sveltejs/devalue/commit/dae8153e9d7541b975cc4018138d6cebec6c1199"},{"type":"PACKAGE","url":"https://github.com/sveltejs/devalue"},{"type":"WEB","url":"https://github.com/sveltejs/devalue/releases/tag/v5.9.3"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-01T15:30:10.729813749Z"}}
