{"schema":"threatline.record/2","record":{"id":"GHSA-x5rw-q4pp-hg5g","aliases":["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.","categories":["Libraries & packages"],"product":"devalue","vendor":"","ecosystem":"npm","affected_ranges":[{"source":"GitHub Advisory Database","source_url":"https://github.com/advisories/GHSA-x5rw-q4pp-hg5g","source_modified_at":"2026-10-01T15:15:15Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"ecosystem":"npm","name":"devalue"},"range":">= 5.8.0, <= 5.9.2"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-x5rw-q4pp-hg5g","source_modified_at":"2026-10-01T15:30:10.729813749Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"devalue","ecosystem":"npm","purl":"pkg:npm/devalue"},"ranges":[{"type":"SEMVER","events":[{"introduced":"5.8.0"},{"fixed":"5.9.3"}]}],"versions":[]}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/advisories/GHSA-x5rw-q4pp-hg5g","source_modified_at":"2026-10-01T15:15:15Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"ecosystem":"npm","name":"devalue"},"version":"5.9.3"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-x5rw-q4pp-hg5g","source_modified_at":"2026-10-01T15:30:10.729813749Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"devalue","ecosystem":"npm","purl":"pkg:npm/devalue"},"version":"5.9.3"}],"cvss":8.2,"severity":"High","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-01T15:15:13Z","modified_at":"2026-10-01T15:30:10.729813749Z","provenance":[{"source":"GitHub Advisory Database","url":"https://github.com/advisories/GHSA-x5rw-q4pp-hg5g","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-01T15:15:15Z"},{"source":"OSV","url":"https://osv.dev/vulnerability/GHSA-x5rw-q4pp-hg5g","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-01T15:30:10.729813749Z"}],"sources":["GitHub Advisory Database","OSV"],"references":[{"url":"https://github.com/sveltejs/devalue/security/advisories/GHSA-x5rw-q4pp-hg5g","source":"GitHub Advisory Database"},{"url":"https://github.com/sveltejs/devalue/commit/dae8153e9d7541b975cc4018138d6cebec6c1199","source":"GitHub Advisory Database"},{"url":"https://github.com/sveltejs/devalue/releases/tag/v5.9.3","source":"GitHub Advisory Database"},{"url":"https://github.com/advisories/GHSA-x5rw-q4pp-hg5g","source":"GitHub Advisory Database"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"ecosystem","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-01T15:30:10.729813749Z","content_hash":"401ea9208dda6d85c2e73369e079f092b9eac9dececc600aeedb964fe9108b18"}}
