Furthermore, object(s) of sensitive nature would have to be stored as metadata, before this can become a vulnerability.\n### Patches\n\nHas been patched in version `0.6.1`.\n","aliases":["CVE-2023-30857"],"modified":"2023-11-01T05:01:58.138414Z","published":"2023-05-01T14:01:02Z","database_specific":{"severity":"LOW","github_reviewed":true,"github_reviewed_at":"2023-05-01T14:01:02Z","nvd_published_at":"2023-04-28T21:15:09Z","cwe_ids":["CWE-1321"]},"references":[{"type":"WEB","url":"https://github.com/aedart/ion/security/advisories/GHSA-wwxh-74fx-33c6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-30857"},{"type":"WEB","url":"https://github.com/aedart/ion/commit/c3e2ee08710d4164d796ecb66ed291335dae9291"},{"type":"PACKAGE","url":"https://github.com/aedart/ion"}],"affected":[{"package":{"name":"@aedart/support","ecosystem":"npm","purl":"pkg:npm/%40aedart/support"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.6.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/05/GHSA-wwxh-74fx-33c6/GHSA-wwxh-74fx-33c6.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N"}]}
